You remove the first widget (by just destroying it, or
gtk_container_remove()), then pack the other one.

Try gtk_box_reorder_child() to move the newly-packed widget into place.
You could also add an additional container (such as another box, or a
GtkEventBox, or GtkAlignment) and use that container as a "socket" inside
the first box, so you can add/remove widgets from it.
