Jimmie, it looks like what you want to do here is build a standard user interface so actually what you want to do is to use Spec. Below are some pointers from a mail of Sven VC of some time ago. Note that you can now also integrate GT presentations as widgets inside a Spec UI, in case you want to reuse e.g. the GTInspector inside your UI.

Here is a guide to documentation about Spec, most recent first.
There is an excellent presentation by Johan Fabry did during the last Pharo Days, 'Using Spec to Build a UI'. *MUST WATCH* (the video is not yet fully public, but soon will be, the link should work though):
http://youtu.be/OL23s9ZUIR0?list=PL4actYd6bfnz98ngrKALwwStl3C3odEKGThe slides are also not yet available, but soon will be (the talk is much better that the slides on their own).
This draft chapter 'Spec: a framework for describing user interfaces' for an upcoming book:
https://ci.inria.fr/pharo-contribution/view/Books/job/PharoBookWorkInProgress/lastSuccessfulBuild/artifact/Spec/Spec.pier.htmlLook in the image.
Browse the hierarchy below AbstractWidgetModel in the category Spec-Core-Widgets in Pharo 4, look at the protocols called 'protocol' & 'protocol-events' mainly. Look for references to each class. Trace senders of methods until you arrive at examples. Study the examples, play with them, change them.
The UI of most tools in Pharo is also implemented using Spec. Browse the hierarchy below ComposableModel to find them. (Komitter, Versionner, Critics, Metacello, the old Eye Inspectors, ..). Watch and learn.

It will only contain a few 100 or 1000 items. I don't see a need at the moment to involve MongoDB or some other outside source. I will have an export/import mechanism for data safety.

It seems that GT is where UI things are moving. Just a perception. I could be wrong. If possible I prefer going with the future as opposed to legacy at this point.
