Javascript – HTML/JavaScript UI widgets GUI builder

javascriptuser-interfacewidget

I've heard and used some of the libraries like Ext JS, qooXdoo, jQuery UI, dijit. I know there are unofficial attempts to create GUI builders but they are not really great.

Any chance there is a HTML/JavaScript UI widget library with a decent GUI builder?
