If the languages differ in the direction of reading
(LTR<->RTL), more has to be done.  Calling
gtk_widget_set_default_direction() with the direction
obtained from _("default:LTR") will generally take care of
it, though corner cases can remain.  Also labels (and input
widgets) possibly containing numbers or date & time have to
be rendered again, regettexting is not everything.  And
there are other regional settings you either have to deal
with or it's unclear what to do with upon a switch.  So,
impossible is probably a too strong word but maintenance
nightmare it definitely is.
