Look at the libgnomeui or libgnomecanvas libraries, in the glade
subdirectories.

They have libglade plugins for handling their widgets.

If your widgets are completely configurable with object properties, I
think your glade_module_register_widgets() function only needs to call
glade_register_widget() to register each widget and glade_provide() to
register the library.
