A call to gtk_object_destroy is usually the right thing. For a top level 
widget, destroy makes it "self-destruct" and it ends up unref'ing itself 
too. For other widgets, destroy typically causes its container to unref it.

Since you aren't holding a ref to the widget, you can't unref it. And if 
you were holding a ref to it, unref'ing it wouldn't make it go away since 
its container (or itself if it's a top-level widget) is still holding a 
ref.
