HI,
The Apple IDs from @mac.com and @me.com (Older MobileMe and more recent iCloud Names) are also Valid AIM Screen names.
Any other sort of Apple ID is not a Valid AIM Name.
A Google ID that is associated with Google Mail Account (And has "Talk" enable on your Google Settings) can be used in iChat as  Jabber Name/ID.  (Google Run  Jabber server).
Jabber and AIM are different IM Services and it is not easy or straight forward to add Buddies from one Service to the Buddy List of another.  (As A Starting point consider it "impossible")
iChat 4 and 5 have links to the registration page of @Mac.com here with a "Get an iChat Account" button in the add (Account) screen  (You select @mac.com or MobileMe and then press the Button - Choosing AIM and then pressing the button used to lead to the AIM registration page but AIM moved their page).
Apple IDs can be any valid email (or an @mac.com or iCloud registration)
Therefore you could make a Google ID into an Apple ID.
However this will not be a valid AIM Screen Name the way @mac.com or MobileMe/iCloud ones are.
