Desktop application for my URL shortner

I would like a nice simple desktop application for my URL shortner at http://wiurl.com. Users should be able to login create short urls and have custom urls. Also I would like it to have a screenshot app built in where you can use keyboard shortcuts to automatically take a full screen or selection screenshot. Much like tinygrab ([login to view URL]) It would be nice, if possiable, if users could also upload photos from the desktop app. I have a back end php API if that helps.
