I am working on a Python UI (PyQt4) to a Fortran program. The approach I've
taken is to build the Fortran code as a DLL (or .so). Python can load the
library and call a procedure that initiates execution. I'm using sockets to
pass data of different types back to the Python program. This is a work in
progress, and I'm learning Python as we go.
