Perhaps you could try the simplest possible way of running things as a test:

XWin :0 &
DISPLAY=:0.0 xterm

If I understand correctly, this gives you a server window (titled 
"Cygwin/X:0.0"), but no xterm window inside it.

If the xterm client can't connect to the server, this might be due to a 
interference from some firewall software (as the Cygwin UNIX domain 
socket used here is emulated by Cygwin using a loopback TCP/IP socket).
