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. Al presionar cualquier tecla.#!usr/bin/python

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.
