title: How to build 'Gmail notifier' like tool?
body: <p>It would be a nice add on to my web application - a gmail notifier like tool.  Basically the user configures it, it runs in the system tray and pops up a 'balloon' to notify him.  I am a web developer, I don't know where to begin writing such a tool.  Can someone point me in the right direction?  I know Java and PHP, if that matters.</p>
