Q: On icalendar with GMAIL

Gmail?

Syncing with Google's Calendar is nothing to do with iCloud. Have you tried Google's Support forums?

My guess is you've enabled Calendars when setting up your GMail account. If you don't want it, just delete the account from Calendars Account preferences.

Why not just turn Calendars off in System Preferences>Mail Contacts and Calendars.

Well, he could do, but we don't know what version of OS X he's using, so that System Preferences pane may not be there.
