It's strange that GTK doesn't use signals here. You can use cffi:defcallback however:
(gtk:define-application (:name test-menu :id "okaynoobz.org")
(defun test-menu-menu ()
(let ((menu (gio:make-menu)))
(let ((submenu (gio:make-menu)))
(gio:menu-append-item submenu (gio:make-menu-item :model menu :label "Load Excel File"
:detailed-action "app.open"))
(gio:menu-append-submenu menu "File" submenu))
menu))
(defun setup-file-dialog ()
(let ((dialog (gtk:make-file-dialog)))
dialog))
(cffi:defcallback file-open-callback :void ((file-dialog :pointer)
(result :pointer)
(data :pointer))
(declare (ignore data))
(setf file-dialog (gobj:pointer-object file-dialog 'gtk:file-dialog))
(funcall
(gtk::attach-restarts
(lambda ()
(let ((gfile (gtk:file-dialog-open-finish file-dialog result)))
(format t "~A~%" (gio:file-path gfile)))))))
(gtk:define-main-window (window (gtk:make-application-window :application gtk:*application*))
(setf (gtk:window-title window) "Test Menu")
(let ((action (gio:make-simple-action :name "open" :parameter-type nil)))
(gio:action-map-add-action gtk:*application* action)
(gtk:connect action "activate" (lambda (action param)
(declare (ignore action param))
(let ((dialog (gtk:make-file-dialog)))
(gtk:file-dialog-open dialog window nil (cffi:callback file-open-callback) (cffi:null-pointer))))))
(let ((window-box (gtk:make-box :orientation gtk:+orientation-vertical+ :spacing 0))
(menubar (gtk:make-popover-menu-bar :model (test-menu-menu))))
(gtk:box-append window-box menubar)
(setf (gtk:window-child window) window-box))
(unless (gtk:widget-visible-p window)
(gtk:window-present window))))from cl-gtk4.

Okay, that does work with a small problem though. When cancelled, it shows an error as the gtk:with-restarts catches it. I tried ignoring the errors but that doesn't work. This solution doesn't work either but I got pretty far after learning callbacks...
(gtk:define-application (:name test-menu :id "okaynoobz.org")
(defun test-menu-menu ()
(let ((menu (gio:make-menu)))
(let ((submenu (gio:make-menu)))
(gio:menu-append-item submenu (gio:make-menu-item :model menu :label "Load Excel File"
:detailed-action "app.open"))
(gio:menu-append-submenu menu "File" submenu))
menu))
(cffi:defcallback file-open-callback :void ((file-dialog :pointer)
(result :pointer)
(data :pointer))
(declare (ignore data))
(setf file-dialog (gobj:pointer-object file-dialog 'gtk:file-dialog))
(funcall (gtk::attach-restarts (lambda ()
(let ((gfile (gtk:file-dialog-open-finish file-dialog result)))
(format t "The filepath: ~a~%" (gio:file-path gfile)))))))
(cffi:defcallback file-cancel-callback :void ()
(format t "Actually runs???!?!?!~%"))
(cffi:defcallback file-cancel-destroy-func :void ((data :pointer))
(declare (ignore data))
(format t "Please run~%")
(gtk::destroy-all-windows-and-quit))
(gtk:define-main-window (window (gtk:make-application-window :application gtk:*application*))
(setf (gtk:window-title window) "Test Menu")
(let ((action (gio:make-simple-action :name "open" :parameter-type nil)))
(gio:action-map-add-action gtk:*application* action)
(gtk:connect action "activate" (lambda (action param)
(declare (ignore action param))
(let ((dialog (gtk:make-file-dialog))
(cancellable (gio:make-cancellable)))
(gio:cancellable-connect cancellable
(cffi:callback file-cancel-callback)
(cffi:null-pointer)
(cffi:callback file-cancel-destroy-func))
(gtk:file-dialog-open dialog window cancellable
(cffi:callback file-open-callback)
(cffi:null-pointer))))))
(let ((window-box (gtk:make-box :orientation gtk:+orientation-vertical+ :spacing 0))
(menubar (gtk:make-popover-menu-bar :model (test-menu-menu))))
(gtk:box-append window-box menubar)
(setf (gtk:window-child window) window-box))
(unless (gtk:widget-visible-p window)
(gtk:window-present window))))Kindly explain to me where I went wrong. Thanks.

You may try this to ignore errors from GTK:
(alexandria:when-let ((gfile (ignore-errors (gtk:file-dialog-open-finish file-dialog result))))
(format t "~A~%" (gio:file-path gfile)))from cl-gtk4.
