You need groups for the geometry in the .obj file.  You can do this in UVMapper, possibly the original application, or in Poser's Setup Room.  Best to use anything but the Setup Room.  Each group (g in the .obj file) represents a body part.  For something like a robot, you then rig but you might want to sets bends to 0 except where the robot might have flexible joints (think "Lost in Space" Robot's arms here).
Don't know anything about Wings.  Look for Wings->Poser tutorials online or here in the Tutorials section.  UVMapper is a good idea if there is no easy way (but I'm sure that I've read that Wings can do this, I think?).

C makes it easy to shoot yourself in the foot. C++ makes it harder, but when you do, you blow your whole leg off.
