-
it makes perfect sense in C, as Gtk+ has its own object system.
it returns a GtkWidget, but you can just use the macro:

GTK_MENU(widget); 

to cast it as a menu.

i think that the bindings should be as accurate as possible so:

bless(bless $objectmenu->get_menu, 'Gtk::Menu');

oh well, whatever.
