there is a short-hand function that just does return TRUE and hides the window:
gtk_widget_hide_on_delete(). you use it as simply as

gtk_signal_connect (GTK_OBJECT (window),
                    "delete-event",
                    GTK_SIGNAL_FUNC (gtk_widget_hide_on_delete),
                    NULL);
