Front End for Simulator

I am working on a 3D driving Simulator that was developed using OpenGL. (Check the “Need Better Performnce!!!” thread by KGT). I have the job of putting the front end together. The vision for the front end is something that would look similiar to Need for Speed or Midtown Madness. I am not sure if this is possible if OpenGL is used since these front ends seem to be HTML/DHTML based. Does anyone have any ideas or experience that would be helpful?
