Windows has the \"system tray\" that houses the clock and alway-running services like MSN, Steam, etc.
I\'d like to develop a wxPython tray application but I\'m wonderin
wx is a cross-platform GUI and tools library that supports Win32, Mac OS X, GTK+, X11, Motif, WinCE, and more. And if you use it's classes then your application should work on all these platforms. For system tray look at wxTaskBarIcon (http://docs.wxwidgets.org/stable/wx_wxtaskbaricon.html#wxtaskbaricon).
