Hi,
Just came across this old un-answered post while browsing around. I guess the problem has been resolved by now but, for what it's worth, I should think it would be best to stick with one of the many proprietary family tree programs. Then you will be able to print it out or export the data as a GEDCOM if you want to share it.
Having experimented with various spreadsheets, dBase, etc. I soon discovered you can spend more time working out how to organise the data than you spend 'inputting' it.
Mike.
