Ich habe den Code überflogen und den des Layouts mal so angepasst, wie du ihn wahrscheinlich haben wolltest. Die Änderungen habe ich kommentiert, so dass du erkennst, was ich gemacht habe.
Es kann durchaus sein, dass du einige Zeilen des GridBag-Gitters anpassen musst.
Und es sind noch einige unschöne Dinge in deinem Code, die du irgendwann mal verbessern solltest. Zum Beispiel solltest du nun statt im Canvas im von mir angelegten JPanel zeichnen. Dazu ist die paintComponent()-Methode zu überschreiben.
