Group items to task tray

[zone97 9]

I have written a few autoit apps in the past but its been over a year. How hard would it be or is it possible to do the following.

I want to create a program that you can select from a list of running applications to hide their "taskbar" button into the "tasktray" as a pull down or up menu. It will need to remember these programs so that when the autoit app is running to move them into this list?

Thanks for any suggestions or help.
