As far as I know, nobody produces nightly builds for windows. Some
outdated information on building hugin for windows is available on the
panotools wiki:

I don't use Windows anymore, so I can't help with building. Even for
experienced Windows developers, it might be easier to install linux and
build and run hugin there...
