There may be an easier way, but one way is to install a 2-second timeout,
then call gtk_main(); in the timeout, gtk_main_quit(). This will work
independently of your main gtk_main(); gtk_main_quit() will only affect
the top gtk_main() on the stack.

So, something like:

static gint 
quit_timeout(gpointer data)
{
  gtk_main_quit();
  return FALSE;   /* removes the timeout */
}

void sleep_milliseconds(guint msecs)
{
  gtk_timeout_add(msecs, quit_timeout, NULL);
  gtk_main();
}

Code is untested, may well be slightly busted.

Just make sure you don't let the user choose the "quit" menu item or
otherwise cause a gtk_main_quit() to be called before quit_timeout()
happens, or you'll get all sorts of confusion.
