The Windows versions of gfortran aren't well written up.  As Brian said, 
cygwin can be recommended.  There you have several choices (all of them 
optional installations from cygwin setup):
gfortran: the 32-bit compiler which uses the cygwin libraries (runs fine 
on X64).  This is part of the gcc which is supported by the cygwin 
mailing list.  A special cygwin license governs your distribution of 
applications built this way.

x86_64-w64-mingw32-gfortran: a "cross compiler" for "native" 64-bit 
Windows, derived from the sourceforge mingw32 project.  It links against 
.dlls which cygwin setup installs in
/usr/x86_64-w64-mingw32/sys-root/mingw/bin/
but there is no automatic library PATH setup, an obscure fact which I 
haven't seen documented.  As far as I know, there is no help forum for 
these Windows cross compilers, but they are of reasonably high quality; 
even the OpenMP implementation has become satisfactory.

A similar cross compiler for native 32-bit Windows.
