Jetty as link between Java and Browser

Chris has annotated Overview of Programming issues with some comments about Jetty.
He pointed to two discussions:
The discussion here talks about it mainly as a rival to Tomcat
The discussion here talks about using it to call a browser and send code to it.
Does Jetty also respond to requests from the browser? (I read both discussions quickly, so I probably missed this).

Chris - do you think it would be within your skills to produce a proof of concept application using Jetty?
Eg a java  application which opens a browser and sends a "Hello World - How are you?" with a Yes/No option box,
and responds "Oh Dear" or "Great!" depending on the option picked,
where the two messages "Oh Dear" or "Great!" are written in the java code, and NOT in the web page with the option box.

If we can write a program that does this, then we can link to JSword from a browser,
and request verses or searches from the browser and have them displayed in the browser.
We can then add new code either by adding java to JSword or by putting Javascript in the web pages (probably both).

Guys, can you think of any other way to create this little application?
