I want to set up an iCloud account on my pc?

I don't have an iphone, ipad, or ipod touch. All I have is an old ipod nano and the ipod shuffle with a little touch screen that I got like three years ago. When I try to login to the icloud it says that I have a valid apple account but not an icloud account. It said to setup the account on one of the devices mentioned above. Do you see my dilemma? Is there ant other way to use icloud, or set up an account than what is listed?

Create a iCloud account from the website of icloud.
