Using NavigationBar to mimic Outlook To-Do bar

I need to create a similar control as the Microsoft Outlook To-Do bar. I can achieve this by
1. using the NavigationBar
2. setting ArePanesVisible = false;
3. and using just one NavigationPane

However, like the To-Do bar, I would also like to add icons text and splitter lines to the bar when it is collapsed. From what I can tell, the NavigationBar only supports text via the Text property. Is it possible to add icons etc aswell and mimic the outlook To-Do bar?

Thanks heaps.
