How do I sync to Google Calendar not Outlook?

I cannot sync my Samsung Galaxy 5 to my Google Calendar using Kies 3. My only choice seems to be Outlook. Is this my only choice? If not, what do I do?

Syncing to Google calendar is a cloud function and Kies is trying to get you a desktop option.

In Settings > Accounts > tap on the Google account you want and enable calendar from the what to sync list.
