Someone tried getting f2py working on pypy a while ago, a quick search turned up http://www.dalkescientific.com/writings/diary/archive/2011/11/09/f2pypy.html and a fork of code at https://bitbucket.org/pypy/f2pypy
Perhaps that could be a starting point?
Yes, definitely, although there are tools which are better architected like fwrap (https://github.com/kwmsmith/fwrap).
I would expect something based on f2py to be the fastest route, though. fwrap would more likely lend to something that could be contributed by and useful to both cpython and pypy-based implementations.
FWIW, another reason why fwrap is popular, besides a better design, is that it can automatically generate Cython declarations for a Fortran wrapper, so it already supports two targets. Adding PyPy as a third one would reduce the need for users to learn new tools. Stefan
