If you call gtk_widget_queue_resize() on the toplevel, it should
cause GTK+ to recompute the layout from scratch; you'll have
to do that manually after changing the widgets.

GTK+-2.0 is better behaved in this area; you should consider
upgrading.

(Note that in GTK+-1.2 and GTK+-2.0, resizable toplevel windows 
won't shrink back when their contents get smaller; to get this
behavior, turn off resizing; gtk_window_set_resizable in GTK+-2.0,
gtk_window_set_policy (window, FALSE, FALSE, FALSE) in GTK+-1.2)
