Sounds like you're catching on.

I'm guessing that you might want to scan the page to a (pbm) file and
work from that while you're trying to get the OCR working just-so. If
xsane runs the scanner every time you try this, that extended wait is
going to be frustrating.
What resolution is your capture? 200-300 dpi B&W is typically
considered to be the minimum.

Were those goodies free? GPL? Then you could just port the relevant
bits to linux and be all set :-)
OCR is not an easy problem.
http://kooka.kde.org/ is only going to be a different front-end and will
either interface with gocr, ocrad, or a commercial app (if you want to
spend $1k on it -- sounds like a $100 donation to gocr or ocrad might
be a good investment :-/

I'm guessing that ubuntu has dpkg.
dpkg -L gocr
dpkg -L gocr | grep bin
might help find it.
