Point me in the right direction please

Ok.  I'm very new to C#.  I'm using Visual C# 2005 Express, to get my feet wet before I take on the large purchase of the Studio.

I've bought several C# books, and am learning more and more about OOP, which is great because now I'm understanding it alot.  Right now, I'm trying to learn with some more hands on. 

I'm trying to create a very simple application.  A shortcut launcher.  The basic idea of the launcher, is to have a 150-200 by 500 or so Form, and I'm wanting collapsable menus similar to Trillian/Yahoo messenger/VC# Express toolbox, where the contacts are.  I've tried emulating this with TreeView/Nodes, but I can't seem to get it to work properly.  Is this the only way to do it?

Basically I'm looking to setup something like this:
- Remote Desktops
   Server1
   Server2
   Server3
- Dev Applications
   Visual C#
+ Internet Links
- Network Software
   Software 1
   Software 2
+ Graphics Applications

Is treeview the only way to go?  Or can someone point me in the direction of another control I should be using?
