In simple cases, you can just pack the things into an hbox, then when
you wish it to go away, use gtk_widget_hide, and then gtk_widget_show
the other. This way, you don't need to ref the widget, and then remove
it. This gets more annoying to code if you are switching between loads
of widgets.

Several gnome-applets use this technique for resizing/reorienting with
the panel.
