Combo box and textfile binding questions

I am looking to have a couple of combo boxes that will have different categories in each one. In multiple text documents id like to have either a comma separated view where it will have the title before the comma and a link to a website in another comma.

Essentially what I am trying to achieve is to have a form where you can choose a link and have it open a browser (or a tab if a browser is already open) and navigate to a website that is selected.

Example:

Google,http://www.google.com
Facebook,http://www.facebook.com
CNN,http://www.cnn.com

Any way I can achieve this?
