Win32 build:
http://killerstorm.xen.prgmr.com/alex/ngccc-0.0.1-win32.zipExperimental. p2ptrade seems to work now, but it isn't secure. (It doesn't check that we're paid before it signs the transaction.)
Instructions are same as for Linux version:
ngccc-cli setval testnet true to configure it to use testnet, and then you can use ngccc-gui.
We'll make a better release a bit later...
