First of all yes it is doable without a lot of effort. Here's a good description that'll tell you what you need: http://www.comand.co.uk/index.php/retrofitting-comand
You basically need some cables to act as looms and some programming is of course needed if your Unit is Locked because of "Theft Protection".
