Romano Signorelli (http://www.blueskysoftware.it/) has created a standalone question editor for the jQuizShow. It can read and write the tab-seperated database that jQuizShow uses for its questions. See the screenshot on the jQuizShow home page (http://quizshow.sourceforge.net/download.html#Contributions), or just download it from the "Files" page and give it a try.
For Microsoft Windows platform only. Executable and source code (Delphi 5) are included in the ZIP file.
jQuizShow is a Java-based game modelled after the "Who Wants to Be a Millionaire" TV game show.
It runs on any platform which has Java Runtime Edition (JRE) 1.3.1 or later installed (Windows, Mac OS/X, Linux, etc.).
See: http://quizshow.sourceforge.net/ for screenshots and more information.
