I've heard of D-Fend, a sort of GUI or at least "control program" for the DOS-BOX. Maybe it's even in German. ;-)
You could try ask someone in the German section, especially
here, where some have erected a small FAQ for the DOS-BOX. There are also some links in it.
Don't hesitate to ask there, we all can speak English. <img src="/ubbthreads/images/graemlins/winkwink.gif" alt="" /> (Well, at least most of us. <img src="/ubbthreads/images/graemlins/winkwink.gif" alt="" /> )
