With regards to your original question. I used Ubuntu back in the days of Hoary Hedgehog and liked it a lot. I did try it with the KDE desktop (as in Kubuntu) but somehow it didn't seem to work as well, for me the Gnome desktop just seems to run better with Ubuntu However, it may have come on a lot since then?
As a fanatical Zenwalk user I am tempted to recommend that but it may be a bit TOO different for you. Ubuntu/Kubuntu is certainly very good and does have excellent support in the forums.

WINE is one option but what kind of software are you talking about? Linux (and Ubuntu in particular) provides a large selection of kids games and educational software. My youngest loves Tuxracer and Tuxpaint. There is also an excellent educational games package called Gcompris that my kids like. It has things like space invaders with maths sums instead of aliens.
