I doubt anyone has written a native Swing implementation. I dpn't believe that
would be such a great idea anyway. For some of my reasons, see

I think the major problem is that you'd require a free software VM to use a
specific graphical toolkit for their AWT, in order to be able to interface with
your Swing implementation. Whichever toolkit you pick, you'll end up alianating
some people.

If you go the pure java route, you can mostly avoid that problem.

There are actually some java graphical toolkits (Zawal) that are Swing like and
available under free software licensing terms. If you want to look into
extending stuff, then creating a javax.swing wrapper for Zawal might be a
better plan than to try to extend Biss AWT. Especially since Zawal is actively
maintained ;)

On the other hand, there are parts of Swing that can be implemented without AWT
(the html parsing, for example). You could start with that and tackle the Swing
component issue later.

In any case, you should get in touch with Hans Peter from the above cited post,
as he seems to have some ideas similar to yours.

Well, I've heard that the mauve project is looking for (non-interactive) AWT
tests, so I bet they could use someone to write tests for AWT classes.
