I do not build petsc4py on Cygwin, nor Windows. A necessary first step
is that PETSc can build itself as DLL's. Note that you should be able
to build petsc4py without DLL's, however you will not be able to use
any other code that uses PETSc (like SLEPc and slepc4py). I do not
have this issue with mpi4py, as I can download a binary installer with
pre-built DLL's. Unfortunately, I do not have the
expertise+time+interest to get PETSc working on Windows. Once you have
PETSc DLL's, getting petsc4py is just a matter of 15 minutes of
hacking and testing.

BTW, what errors do you get when trying to link petsc4py on Cygwin?
