I don't know what version of nwc2ly you're using, but I rewrote the 
original one to use for converting nwc text files to liliypond.  There 
are instructions on how to use it here:

http://www.holmessoft.co.uk/homepage/software/NWC2LY/index.htm

This covers creating 4-part choral scores automatically - please see the 
page on "voices".  The instructions also link to a zip file with the 
required .exe files and a document with extra commands.

Hope that helps.
