Add a new item to the Server Explorer windows using VS 2010 Package

Hello,

how can I add an item into SE window?
I have added a button into SE toolbar that opens a window which should add an item into SE


Now I have to add this new item - "tree" with sub-options to the Server Explorer after "Data Connections" and "Servers". May be some suggestions?
