It is my understanding that an HDTV, with Internet capability, has widgets. These widgets are software utilities that let this TV, if connected to the Internet, surf to a few selected Internets sites that the widget(s) support.

Is there a wireless hardware system that would display anything that is on my PC's screen to my HDTV?

Thanks.

I'm not sure where you're heading with the widgets, but wireless PC-to-TV converters exist. Examples: Kworld PlusTV Wireless PC To TV Converter - 2.4 GHz.
