Das "samt GUI" kommt mir komisch vor. Natürlich kannst du Klassen in Klassen (anonym, inner) legen. Auch kannst du Klassen in anderen Klassen verwenden, sonst würde das ganze SDK zusammenbrechen. Wenn du eine grafische Komponente willst, die du mittels eines Layouts einbinden kannst, dann erbst du einfach nur von JComponent (sofern du Swing verwendest, was anzuraten ist) oder einer passenden Kindklasse (z.B. JPanel). Dann änderst du eben genau das, was du möchtest und fertig ist deine Komponente.
Wie meinst du das ? Alles in der anderen Klasse auf JPanel, JButton, JLabel,…. Und dergleichen beschränken ?
