Several years ago, I wasted countless hours trying
to get FORTRAN and IDL to work together via CALL_EXTERNAL.
The problem, I eventually found out, that you
can (safely) do NO I/O in the FORTRAN code. FORTRAN
I/O through CALL_EXT will seem to work Ok on some
platforms, but will break IDL on others.
This warning is now added to the IDL
documentation - do not ignore it! If your FORTRAN has
I/O scattered throughout, you will have a
rough time.

If your GUI does not have to be extremely complex,
you can write it directly in FORTRAN. Check out
