I guess so, but need to wait until I upgrade my Tk. Or a promised Zooz release that would work with a more general Tk version...

But both tools have different targets, though.

UPDATED

I have installed and tryied ZooZ in my Windows XP Pro successfully! It is great, and as simple as using M$ Visual things :)!

This is a great achievement to perl and Tk... Though it needs more time to standarize well.

Both tools that I have tried have very creative ways of approaching the GUI dessign. ZooZ looks more interested in getting the result. But both are very encouraging for using Tk in the daily script development.
