I don't know much about gmail and don't want to know any more than necessary, but I think:

If you have a gmail account the account name will be whateveryoupicked@gmail.com I don't think you can have a gmail account any other way. (You can have a youtube account with some other account name.)

If you haven't created an account with whateveryoupicked@gmail.com, and you want one, then you need to create one.

If you think you have already created a gmail.com account, then you better start remembering what name and password you chose.

I'll bet this doesn't help.
