How do I connect PC to PC with a gmail account?

I have all my stuff setup with my email account and password. email is not a gmail account. I then went to my PC that I am going to use to connect to other PC's with. I installed the Jump Viewer on the PC I am going to use to connect to other PC's with and the only option I see is to connect using a gmail account. I dont have a gamil account and don't want  gamil account. So what can we do to fix this problem?
