Hm, you are right. You can pop up individual menus with this code:

gboolean
on_MainWindow_button_press_event           (GtkWidget       *widget,
                                       GdkEventButton  *event,
                                       gpointer         user_data)
{
   GList *l;
   l = gtk_container_get_children(MenuBar);
   gtk_menu_popup(gtk_menu_item_get_submenu(l->data), NULL, NULL, NULL, 
NULL, event->button, event->time);
}

The easy solution would be to dynamically create the top menu by 
scanning the menubar children and then set the various menus as submenus.
You will then have to set the menus back to the menubar on popdown. A 
bit convoluted, but it avoids duplicating your menus.
