As mentioned by others, there are already libraries that can do this.
If you want to cook your own, you do need to exercise some care.  All
Fortran compilers I know of have, essentially, a C-compatible
interface.  The only thing you need to know about is how Fortran
handles strings.  

If the existing libraries don't do what you want, please ask again
here, and we can help with setting up a call to a Fortran routine.
