Fox was the best part of Acces (the GUI builder, but way better) + a capable embedded database engine + way better language than anything else for businesses apps.
This could sound weird, but even python is to hard in contrast with fox. Also, being more database focused, interactive and with decent GUI abilities was a match in heaven.
Fox is still pervasive in my country in a lot of simple apps/POS systems. Is the perfect match (you can even provide custom report, form building, etc to end user using exactly the same tools that fox give us). Not was uncommon that some folks at that small companies learn a bit of fox to customize their apps.
My current dream is try to build something like this, and salivate what will happens if also put spreadsheet there with true relational support. Is a pipe dream, because this require a dedicated team and funding, and this kind of "unsexy" tool not fly anywhere.
