If I'm understanding what you are asking, why not put an icon in the
menu bar? I'm referring to the icon(s) to the left of the clock, e.g.
volume, Wi-Fi, Bluetooth, etc. The pertinent classes are NSStatusItem
and NSStatusBar. (Be sure to read the usability notes in the latter.)
Several applications use this for what I think you describe. (I
currently have NSStatusItems from Tweetie, Dropbox, and Growl.)

See NSPreferencePane, probably by way its associated Programming Guide
at
http://developer.apple.com/library/mac/#documentation/UserExperience/Conceptual/PreferencePanes/PreferencePanes.html

I will let someone more experienced in these matters address this issue;
I will note that Dropbox, Google Notifier, and QuickSilver all fit your
general description and are all in Applications. This does not mean you
won't have a LaunchDaemon or the like to get things going as well.
