	gtk_object_destroy(GTK_OBJECT(foo));

For widgets,
	gtk_widget_destroy(GTK_WIDGET(foo));

will do almost exeactly the same thing, but hide the widget before
destroying it.

However, most of the time you do not have to free it up at all. When you
add the label into a container, for example, the container assumes
ownership of the label via a refcount, and the label is destroyed when the
container is destroyed.

I'm sure there's a good gtk+ tutorial out there somewhere,
