Desktop IDE-Style Layouts on the Web

I am making a single-page, full-screen web application which will have a similar interface to an IDE (with menus at the top, output pane on the bottom, and input panes tiled horizontally across the middle). I am targeting only modern browsers, so a solution that uses HTML5 would be fine. Is there a good JavaScript framework and/or CSS framework to make creation of the layout easier?

Update: To clarify, I am looking for tools to make the single-page, full-scree开发者_如何学JAVAn layout practical, not the controls.

Tons. ExtJS, jquery UI, YUI can do it, dojo can do it, many, many others.
