When you signed up with Apple to create an Apple ID did you also setup that ID as an iCloud account? Note that must be done on a Mac or an iOS device.
Which says in part:
You can sign up for iCloud on an iPhone, iPad, or iPod touch with iOS 5 or later, or through System Preferences on a Mac with OS X Lion v10.7.4 or later. Just follow the setup instructions for your iOS device or Mac.

You can't create an iCloud account on a Windows machine, set ip up on an iPhone/iPad, or a Mac.
