I had to check if the creator is Polish, as "ciekawa" means "interesting". But apparently, just a coincidence.
Well, GNU Kawa is named after the Polish word for coffee (going with a play on Java rather than a play on Scheme like Guile and Larceny EDIT: and Gambit went with).
Coincidentally, Chi-kawa is a very popular anime character in Japan.

It's a portmanteau of "Chiisai" (small) and "Kawaii" (cute).
