Hello,
I am a software developer and I have already developed several similar widgets in Flash, including a YouTube widget using Adobe AIR. Please have a look at my portfolio for a sample of my work:

The YouTube widget is at: [

I could develop the widget in the platforms you mentioned. However, for efficiency, and to reduce the costs, it could be a good idea to choose one single, cross-platform engine, such as Adobe AIR. We can you discuss all this into more details by email if you wish. Feel free to contact me at [

Best regards,
Laurent
