Well, you're mostly right - to do something this specific, you need to 
write a more specific module.  I have included one here as a guide.
There are a couple of ways to display values.  The one I've included
uses a floating point 'typein' widget, but other choices available are:
string and string-block widgets (I've used this for the 'Position' label)
and even generating labels as Geoms and displaying them with the Geom 
Viewer.  Take a look at this example, good luck, and don't be afraid to
RTFM.  Developer's Guide: A10-13
