For delete_event your function should be:
gint quitt_app(GtkWidget* window, GdkEventAny* event, gpointer data)
{

  return FALSE;
}

Is quit_app() static or member? If it's a method then it won't
work. If it's static then it should, but technically isn't guaranteed
to; you may need to put it outside the class and declare it extern
"C".
