Not completely sure I understand what you need. The XMLisp approach (http://code.google.com/p/xmlisp/) is to create GUIs as DOM-like structures of 2D (Cocoa controls) and 3D (OpenGL views). The controls are platform native (OS X, Windows). Control actions are written in Lisp in a way to make it quite simple to mix 2D and 3D content.
