Aber ich habe noch nicht die lösung gefunden, daß
Hinzufügen, Aktualisieren und beenden unter Label kommt und nicht Links unten.

Kann jemand helfen? Ich mach mal ein Foto, wenn das klappt.

Und warum benutzt du nun nicht den visuellen Designer?

Beispiel

Ich weiß nicht was du hier machst.
Der Code kann überhaupt nicht laufen.
Das ffängt bei
jframe.setDefaultCloseOperation(JFrame.EXIT_ON_CLO SE);
und
ddComponent(button_add).addComponent(button_upda te).addComponent(button_abort)
an und endet hier

Was soll das?
