Because several people would like them: here are the sources of the 1.4 version.
I just zipped my entire source directory (including build, dist, ...), so everything should be there. Also note I created the app with NetBeans 5.5, to edit the just open the source-dir and everything should work fine (you'll have to add the iText library to the NetBeans libraries though).
Note: these sources don't include the iText library I used. Visit http://www.lowagie.com/iText/
to get the sources or binaries.
A little disclaimer: It has almost 5 years since I last wrote something in Java (and the first time using an IDE, in college we had to use notepad/emacs so we wouldn't be 'spoiled' by the IDE's features). So if you see something strange/funny/stupid in these sources, please inform me ... I didn't take (yet) the time to 'clean up' these sources
