I have looked around once or twice for a PostgreSQL source for NT, but 
didn't find any
pre-built binaries on the postgresql ftp site.  Did you build it 
yourself from source under Cygwin?
Any special advice?

There isn't really anything special with regard to PostGIS integration 
with libpq.  Once you know
the SQL to use interactively with PostGIS, you just do the same thing 
through libpq.  There is
respectible libpq documentation on the postgresql web site.

There is an example of code using libpq with postgis in my GDAL/OGR 
library.  If you want
to look at it download the following and look in gdal/ogr/ogrsf_frmts/pg.
