Un Label no es ningún dibujo ni nada, es una ventana, por lo tanto tiene un hWnd.

Lo que ocurre es que es una ventana hija de la instancia de tu aplicación, y para encontrar su hWnd primero debes encontrar el de la madre y luego usar la api EnumChildWindows para que te liste todos. O más fácil: con Label.hWnd y listo, jaja, sin tanta complicación.

Para obtener lo que tiene escrito es con GetWindowName().
