This is strange. I wanted to put together a simple UI for stepping thru large quantities of data. I'd have normally done this via Tcl/Tk which provides a great environment for quick and dirty UIs, and has the added benefit that I'm very familiar with it.
I have to think thru the back-end capabilities a bit; it may get complicated navigating a very large record set controlled via the browser. If it does work out, it'll be a very nice separation of logic and UI.
But the main surprise for me was, I now consider AJAX simpler than Tcl/Tk for these types of tasks. Given that I complained about AJAX's learning curve earlier, I've had quite a change of heart.
