Alternative Java or C# UI libraries targeted at gaming
Other than AWT, Swing, SWT (Java) - are there any good open source Java or C# UI libraries around?  In particular, libs intended or at least usable for strategy gaming dev?  (The visual appearance of the UI would need to be highly dynamic and easy to re-skin obviously.)  Engines or "frameworks" which include this functionality are valid answers as well (of course I even more doubt that those exist).

As far as I can tell - there's not a single thing like this out there. Anyone able to prove me wrong?
