awesomium

High-level Awesomium bindings.

Awesomium (http://awesomium.com) is a windowless port of Chromium/Webkit.

You can integrate it with your program, and write all of your UI with HTML/CSS/JS.

If you plan to integrate Awesomium with GLUT you can also check out this package (http://hackage.haskell.org/package/awesomium-glut).
