I had the same idea! Converting the VB code to visual basic is one part (the easy part) but I don't know how to build that kind of interface in VB. Even if I did, a scene needs more than just windows and some scripting has to be involved. No GUI can come up with a flexible way to achieve that. Of course, it is possible to make simple stuff like managing sub scenes and handling command windows, but it makes me think is it really worth all the time and effort?
Just to be clear, I'm not going to be a part of this. Sorry. If anyone does this though, all the best
