Add group to an existing MS Office Ribbon tab

Question

I'm looking for a way to programatically add a group to an existing tab (e.g Developer tab in my case) of the Microsoft Office Word 2010 ribbon.

Cannot find any helpful examples on the web. Are these types of customizations allowed in MS Office 2010 and if so could you please provide any helpful links or a code sample on how I can do this
