I don't know for sure but I would guess so. I think a better strategy is
1. destroy your window
2. let GTK+ process pending events in the main loop
3. exit your GTK+ main loop.

Coded it would look something like this:

    gtk_widget_destroy (GTK_WIDGET (window));
    while (gtk_events_pending ())
        gtk_main_iteration ();
    gtk_main_quit ();

Btw, destruction automatically involves hiding of widgets.
