I wrote the main application for my wife's business — she's a psychologist. That was only a few years ago, but as a senior lecturer in the more theoretical parts of computer science, I never really needed fancy UIs with flashy graphical effects. So I built a core engine and used the classic dialog tool as the thin user-facing layer.
At first, my wife was pretty disappointed — as a computer science teacher, wasn't I supposed to know how to build a “real” app? But a few years later, she doesn't want anything else. I even offered to have one of my students create a nicer UI without changing the engine or database, but by now she's completely used to the terminal menus.
The tool keeps a database, collects data through dialog forms, generates PDF invoices with groff, and launches Thunderbird when needed (to send invoices, etc.).
