  I know someone who had a similar problem; I believe that one option is
to keep the widgets created but store them somewhere else in your program.
Then just do gtk_container_remove() on the one and gtk_container_add() on
the other (or table_attach..whatever..)

  The one subtlety is that you have to keep it from destroying the old
widget.  I think there's a call, gtk_object_reference(), or gtk_reference(),
that just increments the reference count of an object (so that it doesn't
get zapped).  You'll want to make sure you dereference it before destroying
it for good, though. :-)
