Well, in trunk you are allowed non GtkWindow toplevel objects, and you are
allowed to use a more lax naming scheme - so it can be as easy as defining some
widget layouts in glade... and then the art is how you parse it with gtkbuilder.

you should be able to use builder first to build your main window, and then
go back in the file and build your other "composed" widgets seperately,
and just add them to your interface with gtk_container_add() yourself.

Glade can also integrate your own real custom GtkWidget derived object
into the runtime, thats why we deprecated the old custom widget hook.
