Formulario Java Jframe con Jpanel no funciona

[GeVi]

Cyrux, lo que quiero decir con que el jframe tiene un usuario y contraseña es porque mi clase menu inicializo el jframe pasandole valores, lo que necesito es que ese jframe cargue una clase externa por medio de uno de esos valores osease el nombre de la clase. anexo codigo a ver si me explico mejor

este es el JFRAME
