How? Do you have some example code showing how this query is retrieved, dealt 
with locally and made available to an end user through a GUI control?
What I am looking for here is a bridge between what experts glean from reading 
Javadoc and what ordinary people need to use Jena within a GUI based 
application.

I see this kind of example as the missing link that prevents anyone other than 
expert using Jena.
So long as easy to follow examples of how to get from an rdf triplestore to 
information displayed on a screen in a standard GUI way are missing, Jena will 
remain a plaything for expert enthusiasts.

You can take a look here, these projects use Jena extensively:
https://github.com/AtomGraph/Core
https://github.com/AtomGraph/Processor
https://github.com/AtomGraph/Web-Client

Make a query that returns a jsonld document.
