How do I add a Google Calendar to my iCal

I use iCal as my main calendar on my phone, however, we have a Google Calendar for our work roster.

I have no problem seeing the shared Google Calendar on my phone, but if I go to iCal on the PC, I cannot see the calendar there. I can't even add any Google Calendars at all. I have spent hours, probably even days going through all sorts of blogs, and apple itself. But no luck. The instructions often say, Go to preferences and click on Accounts. But there is no option for accounts.

Please Help! I really need to see the whole month in front of me to schedule appointments. I cannot do this on my phone and only have a PC. I prefer iCal to Google Calendar, otherwise, I'd be switching.

TIA
