I'm looking to add a button to the titlebar of a window, just like the _X buttons.

An example of this can be seen in the download program GetRight (www.getright.com), in which the individual download windows have an additional titlebar button that triggers minimizing to the tray. (Whew, deep breath)

Anyone know a code-based or component-based way to do this? I don't want to create a button on an empty form and float it above the titlebar of the target form.
