Do you want to put it in the Quick Launch toolbar? First you will need to show the Quick Launch toolbar by right clicking on the taskbar, choosing Toolbar, and clicking on Quick Launch. Then you can just click and drag the app icon onto the toolbar.
I have never tried to put anything in the system tray, like Tony I usually just try to get stuff out of there, it means programs are using resouces.
Hope that helps,
