suggestion to install sys tray icon

[jsbach]

i'm looking for a way to install a sys icon for an application using nsis. Not just a notification icon (i can use notifyicon plugin for that) but a real active icon in the sys bar on the bottom right with a few options like 'About', 'Exit', 'Activate'...
The application is a liveupdate agent written with nsis that i schedule with standard task scheduler. it would be nice thing to have icon in sys bar to manage some quick actions, i.e. disable/enable schedule, change interval, see doc help if any and so on.
any hints appreciated.
tks.

ps. of course i already read existing forum posts but it seems to me not really what i whish to achieve.
