Depends :-) f2py, directly coding C, SWIG.

Yes

As I understand it, ctypes is not really a solution. The code is about
data handling and FE analysis. It has not GUI component. I'm not sure
how well ctypes works with Numeric arrays, but I'm sure ctypes does
not work on Linux and Solaris, but my code has to.
