Seguinte: tem essas classes! Gostaria de saber se são mesmo o View e o Model e o que falta no controler.
Segue as mesmas:

m.atualizaLista(lstFamilias);
setIconImage(Toolkit.getDefaultToolkit().getImage("c:\\ricardo\\telas\\sgod.jpg"));

[/code]
Controler (se falta ou alguma coisa e é mesmo controler):
public class ListaFamiliasC {
public ListaFamiliasC() {
}
public void atualizaLista(){
}
} Por favor, se alguém um idéia melhor ou se isso NÃO for MVC me dá um aviso.
Por enquanto
Obrigado
