Is it an external executable you can use by just passing in a few args from the shell and capturing output? Or do you have a set of number crunching routines you would like to tie together in some sort of OO form? If I assume the latter, then your best bet may be to just use whatever interoperability with C capabilities (without knowing more about your compiler) your fortran compiler provides to create intermediary C wrappers and just proceed from there.
