Also had a short thought about this when it was released. The notion of it is indeed great ;)

Regarding graphical features I think http://h3.gd/code/nucleus is the most advanced project and with a really neat design (read the thesis), but unfortunately dead and the codebase is confusing. (could also be an interesting project to revive that one, many cool projects are rotting there, including a nice OpenGL GUI)

Porting this by hand would be insane. I suggest to work on a C++/D converter based on Clang similar to https://github.com/jacob-carlborg/clang instead which does the nasty part. The Doom code would be an excellent testbed for that tool and it could also be used for other C++ code.

Maybe something like SWIG could be used.
