Here's some PHP code that would enable you to send
Wake On Lan packets to selected devices. You could make this available on a plug running PHP and a web server.
The configurable parts are at the top of the code listing; set the names / IP addresses / MAC addresses according to your needs. The IP address element and the links section are optional.
You can remove the password protection for the web page by changing
$my_password = '123'; to:
$my_password = '';<?php
