If you are doing desktop develoment I would recommend using Swing, IF there is no need to have backward compatibility to really old JVMs. AWT is still in use in J2ME (micro edition) in embedded devices for example. Swing and AWT should not be used together, although some AWT non-graphical components are used also in Swing.
There is also a commonly used widget set introduced by the eclipse project. I haven't tried it but it should be well worth looking into, if not otherwise atleast for pure interest. SWT (Standard Widget Toolki) and info about it can be found from: http://www.eclipse.org/swt/
