Well, here's a starting point.
Running this will display the icon in the system tray and you will see its tooltip by holding your cursor over it.
For further interactions you could just read up on the MSDN articles and set the members of the NOTIFYICONDATA and message parameter of the Shell_NotifyIcon() function accordingly. You will have to receive and interpret windows messages sent from the tray icon to handle it further. This is easily done using BlueGUI if you have that, but there are other ways as well.
To run this code you will need to have Matrix1Utilities. An example icon is attached to this post.
