Bespoke RSS Reader

I need a very small application that users can install easily. It will check every 5 minutes if preset RSS feeds have been updated and alert them via a small pop up with a link to the new item in the updated feed. The key is for simple install. Ideally the program can run in both Windows and Apple platforms. But I am prepared to accept bids for each platform. ## Deliverables This program should require no effort to install on behalf of the end user. It must install so it always runs when the computer is switched on. It needs to be easy to uninstall. The ability to modify the preset feed URLs? must be available. The user should have a set of check boxes to switch off the preset feeds. There is a program call Alertbear at [[login to view URL]][1] - I want something very similar to this but with my feeds preset.
