Creation of Widget Modeled From Website

Hi, I would like to create a widget modeled on my website www.scriblink.com. The widget should look and function exactly like the site. The main purpose is to put the widget on third party sites. Scriblink is built using Java, but I'm not sure if Java can be used to create the widget or if it is the ideal language to use. If you have any questions please let me know... Thanks, Jordan
