Swing (java)

SWING set of lightweight GUI components that give much fancier screen displays than the raw AWT. Since they are written in pure Java, they run the same on all platforms, unlike the AWT. They are part of the JFC. They support pluggable look and feel — not by using the native platform's facilities but by roughly emulating them. This means you can get any supported look and feel on any platform. The disadvantage of lightweight components is slower execution. The advantage is uniform behaviour on all platforms.
