Binding control with seperate window

[Xor1010]

*Edited*

I have some Controls on a Canvas, and each control needs to:

1) Somehow link to an instance of a class that defines more details (this other class will hold specific details - for example - A list of colours, or some specific numbers that are related to that control).
2) When clicked on, have its properties (such as Background,Size, as well as the "specific" class instance properties) edited from a seperate window.

I've had a look at http://www.codeproject.com/KB/WPF/MVVMForDummies.aspx , and I think the MVVM pattern is what I need for this.

Anyone have any pointers?
