Question

Are there any GUI toolkits built on top of HTML Canvas like swing,swt,gtk or qt? So that it is possible to build applications like applets or flex gui:s inside the html canvas.

Mozilla Labs' Bespin project currently uses their own toolkit called Thunderhead. It's written by and for the Bespin developers, but it's a separate project that could be used for anything. You will need a (free) Bespin account to try it, since there aren't any other projects that I know of that use it.

I've never used it, but I know it uses the DOM and a subset of CSS plus it's own CSS-like properties. I doubt the API is very stable though since it's experimental and evolves with the needs of the Bespin developers.

EasleJS is a great framework!

I assumed the OP asks about replacing classical GUIs with Canvas based web-GUIs of which Cappuccino, at least to some extend, classifies. Actually, would you let me know how you interpreted the question?
