1) поскольку начиная с JDK 6, обновление 12 и JDK7, сборка 19, , вы можете легко смешивать тяжелый (AWT) и легкий (Swing) компоненты , но я не Не стоит смешивать AWT с Swing,
2) его сложное изменение Look & Feel для компонентов AWT, я никогда не видел хорошего, по умолчанию есть Look and Feel, который пришел из Native OS, Look and Feel об использовании Swing JComponents
3) поскольку можно ставить JComponents с другим Look и Feel, я бы предложил создать что-то похожее
