It's not clear to me what tools you have. Do you have a Fortran compiler for
Win32? If you do, and if it allows you to build a DLL, then the expedient
thing to do is export your function from the DLL and to call it from a C++
executable. Assuming compatible types and calling conventions VC++ should
have no trouble calling into an external DLL.
I don't believe that MS sells a Fortran compiler. You will find some free
Fortran compilers here:

though I should tell you that I have no experience with any of them.
