I've not specifically tried it with GCE, but a good starting point
might be this Perl script:

I skimmed the GCE requirements, and you'll probably need to modify
that script a little bit, particularly to make the size be an exact
multiple of a gigabyte (currently it uses a fixed 100MB size).  Also
you'll need to modify it to upload your kernel and initramfs instead
of the ones from /boot on the host.
