Look for a package called "Glider Design!" on anonymous FTP sites such as the
rascal archives. It allows you to interactively design balsa-wood gliders,
analyzes the result, tells you what's wrong with your design and how to fix it,
and eventually prints plans for building your glider. It's freeware from the
Michigan Space Grant Consortium, and I think it's wonderful. :-)

Hope this helps.
