Creating an app. with two dockable windows

[Okee]

I've been working on a program that's going to be similar to gkrellm (or, i'd like it to be :-P). I have a main window i've created and a second window that I'm going to eventually plop a bunch of system information output on it. I want the second window to be able to dock with the main window. I've searched codeproject.com, msdn and pscode.com. The examples are either MFC or non-existant. I could find no explanation on how to do so.

Anyone possibly know how to do this or has done it before and wouldn't mind helping me out?
