Package (free or commercial) for building GUI for standalone Java based Application

I am looking to build a Java based GUI oriented stand alone application. I have already tried SWT and S开发者_JAVA技巧wing but the GUI layout lacks the polished look and feel of commercial applications such as the cd/dvd burning software Nero.

Can someone recommend a GUI building library that can be incorporated into Java based applications? Commercial GUI packages are also fine.

Note: This is a standalone application and not web based.

Qt used to have some java bindings (http://qt.nokia.com) not sure if they still do.

You may also want to look into other free or commercial Look & Feel implementations, which can make Swing look quite polished.

Good luck

I've used Griffon in the past although the coding was in Groovy.

Take a look at nimbus. It's the less ugly Swing look and feel.
