As best I can recall, he wrote it in CodeWarrior over a couple weeks together with another guy who presumably knew Illustrator, and Adobe bought it before they had to deal with anything like a business plan.
Wow, that's a name I haven't heard in 20+ years. We used CodeWarrior Pro for my Pascal class at a local community college that I took during high school, because my high school was so small, I literally ran out of classes to take by senior year, so I had to take a programming course at a CC that was 10 miles away. Had to get a waiver to leave school before noon to go to the class because state policy was that students can't be released from school before noon, and because all my classes (all 3 of them) were over by 11:30.
This is actually how I first got into programming when I was younger. I made my first site in ImageReady, but it couldn't do all the other cool stuff other sites did like comment sections and logging in, so I went on a quest to learn how to do all that and the rest is history :)

Edit: actually, I found an example from 13 years ago https://youtu.be/qCq0JiwMcJs
Can you elaborate on this?
You can see this on the main screenshot on the website: http://rangelreale.github.io/htmlbutcher/index.html

For a 9x9 basic table grid you would set the width 100% of the top and bottom image do the opposite for the sides and fix the corners. All of these tricks involved choosing designs that could work.
It would have been a tool I would have liked.
Not counting that some websites had dozens of PSD files, it was a pain.
