Is There an App Like PaintCode for HTML, CSS, and JavaScript?


Earlier today, John Gruber at Daring Fireball pointed out a recently released app in the MacOS X App Store called PaintCode (on the Web, in the App Store).  As the PaintCode website says, "PaintCode is a vector drawing app that generates Objective-C code in real time."

This is a fantastic idea, I'd like more than anything to have a use for it.  The idea immediately sparked a question in my mind:

Has anybody ever developed an app that like this that generates HTML, CSS, and JavaScript?

I could really use an app that generated code for the web in this fashion.

Is the closest thing to this to a code generator for HTML, CSS, and JavaScript the Mac application called Hype?
