ssh can execute commands remotely.  The way I would do that is to create
an otherwise harmless user account on the server and use sudo to give
the account permission to execute shutdown.  Then your script just needs
to execute this

ssh username at server /sbin/shutdown -h now 

in an xterm, which would allow you to type in your password (or ssh
passphrase, if you install your ssh public key on the server).

If you use ssh-agent and ssh-add, you won't even need to type your
passphrase (well, only the once, when you add the key to ssh-agent's
cache), and so can ditch the xterm.

If you aren't familiar with ssh, ssh-agent etc I can go into more
detail.
