  That's a bit of a roundabout way to do it...why not just make a
shortcut to "c:\cygwin\usr\X11R6\bin\startxwin.bat"?

  To preload the username, you need to create ~/.ssh/config and specify
the "User" option.  As for not prompting for the password, to do that
you'll need to create a RSA/DSA key pair and use ssh-agent.  Check out
the following manpages for this stuff:

man ssh_config
man ssh-keygen
man ssh-agent

  You certainly could type "xterm" and have it run...as for doing it
automatically, you might find that running X applications automatically
on login is more trouble than it's worth.  ;)  If you want to, though,
I would imagine you could put "xterm" in your ~/.bash_login or whatever.

  Well of course, that's because the ssh client is forwarding the port
that those applications are using...kill ssh and you kill the port
forwarding.
