Hola! quisiera hacer que mi applet tenga un fondo de color o una imagen, y si es posible que los dos botones tenga/sean una imagen y saber como acomodarlos, darles posicion en el propio applet para ponerlos donde yo quiero, si alguien me puede indicar si esto se puede en el siguiente c?digo y como, le estar? muy agradecido!
