I started working on a Java-based character creator program a few years ago. It got shelved at some point when I got busy with other things. A couple months ago I pulled it off the shelf, blew off the dust, and pounded it to a fairly decent state.
You can use this to create new characters, save them, and export them to an XML file. My next steps are to find or make some kind of HTML-based character sheet I can use as the basis for exporting the characters into a printable state. Anyone who has, or can make, something like that, your help would be greatly appreciated.
Character advancement is not yet available, but is an eventual goal.
If such a thing interests you, please take a look and tell me what you think. You can download it here: https://www.dropbox.com/s/qajrsnfzpxoy2t2/7SCC.zip
