Other Ajax oriented GUI Toolkit

[Plex Toolkit](http://www.plextk.org/trac/wiki)

An XML+Javascript based toolkit that aims developer to make up very amazing interfaces, creating interface in XML format. Can find demo [here](http://www.plextk.org/trac/wiki/Demos).

[QooXDoo](http://qooxdoo.oss.schlund.de/)

QooXDoo is an advanced open-source JavaScript-based GUI toolkit. QooXDoo continues where simple HTML is not enough. This way qooxdoo can help you implement your AJAX-enhanced web 2.0 application - easier than ever before.

QooXDoo also seems to be a very interesting JS Framework to make up beauty interfaces. Demo here.

Ok, everything beauty, amazing, interesting, powerfull… bla bla bla. But, using JavaScript!!! The terrible-ungrammaticated-unportable language trapped in out browsers.

I think that in the future only “complete” solutions as GWT, that aims to write EXCLUSIVELLY Java Code, autogenerating JS code, becomes the MUST for Web-Apps development.
