First you should determine if it is worth accessing that code/program. 
Since you are going to use numpy then it may be worth the effort to 
rewrite the required parts using numpy/scipy/Cython.

If you have no control over the development or it needs to be a 
standalone program then you probably should call it through Python. The 
reason is that you probably have little control over code maintenance 
and how any changes will impact your code.

If the code is a stable then I agree with Rohit that swig is a viable
