If you are a newbie then perhaps learning WPF would be more beneficial if you want to use this ribbon otherwise I would suggest using a WinForms version of the Ribbon as allready suggested.
To use this in WinForms is possible but strongly not recommended unless you are integrating into an already heavily developed WinForms Application that you are migrating to WPF step by step.
Here is some info to help you get started but a Google Search will answer most questions you need answered. http://msdn.microsoft.com/en-us/library/ms742215.aspx The link contains
a walk through from creating the project to a working WinForms application hosting a WPF Composite Control.
Again there really is no point in hosting a WPF Control in a new WinForms App. affectively you will be reliant on WPF anyway and if bandysc is correct WPF wont work on Linux and Mac if that is your target!
If this WPF Control is all you know then stick to WPF unless you have good reason not too :-)
