gtk_widget_destroy calls gtk_widget_unrealize, which emits an
"unrealize" signal. The Button widget doesn't need to do anything
special on unrealization, so it doesn't supply a handler, and the
default handler, gtk_real_widget_unrealize is used.

Which, among other things, includes:
		 
  if (!GTK_WIDGET_NO_WINDOW (widget))
    {
      gdk_window_set_user_data (widget->window, NULL);
      gdk_window_destroy (widget->window);
    }

For more information about realizing, unrealizing, destroying, etc.,
you could take a look at docs/widget_system.txt, though it assumes
a fair bit of knowledge, and won't win any prizes as a work of
literature.

I'll be curious to see how it works out.
