Simple Windows App Needed to interact with itunes and twittr

I won't go into too much detail here but what I need is something similar to this: [login to view URL] but for a windows machine. I want it to have a setting for either constant updating where every time a new song is played (over halfway through) it gets sent to twitter, or manual updating where you press a button in the app, it shows a preview of the current song and how it will send it to twitter and then you send it. Pretty simple app for someone that knows what they are doing I think.
