Do you own Outlook. If you don't you can use OUt look express which comes with windows. You have to go add account and you'll set it up for a POP account. It will ask for POP and SMTP adresses.
GMail has their POP and SMTP settings in the help section. I can't get there now or I'd tell you exactly where.
yeah you just go to tools-> email accounts ... and select add new account.
