It's true -- I just want a simple little data entry tool (which I've got 
now! That was easy.)

I've been doing all of my development by hand, without the luxury of 
frameworks, not out of any programmerly virtue, but just out of 
simplicity -- ie, I've not taken the time to learn about frameworks. It 
sure would be nice to take the time at some point, and I'll keep Tim's 
injunctions about abstraction in mind when I do.

*thanks and joy*
