>From gtk-dialog.ads:
   --  Before entering the recursive main loop, Gtk.Dialog.Run calls
   --  Gtk.Widget.Show on the dialog for you. Note that you still need to show
   --  any children of the dialog yourself.

Gtk_Dialog_Record is a type extension of Gtk_Window_Record, which is a
type extension of Gtk_Bin_Record, so your Gtk_Dialog has a single child,
which you need to show (this child is the VBox described in the
documentation of Gtk_Dialog).

Therefore:
- call Gtk.Dialog.Gtk_New (D).
- Create your widgets, pack them into D.Get_Content_Area
- Create and pack any buttons (e.g. OK, Cancel, Help) into D.Get_Action_Area.
- call D.Get_Child.Show_All;
- call D.Run
