Código:
La aplicación se ejecuta, es decir carga la ventana y también carga el mensaje al hacer clic en aceptar. Pero en la terminal de Eclipse devuelve el siguiente error.

Me he basado para desarrollar esta aplicacion, en el ejemplo TxtCtrl de la seccion "Core Windows Control" del paquete wx2.8-examples. Que copio a continuacion. Y en el ejemplo de http://sccp2009.wordpress.com/widgets para la conformacion de los objetos de la ventana usando los pixeles.
