Hi Lothar,

if the "Visual" in the subject correspondend to GUI, then you are rigth and 
I should start my brain before I answer ... :-)

Your signature includes the link to the Arachno Ruby site. So I combine you 
are familar to this IDE. Has this IDE the possibility to build GUI's for:

- Ruby TK
- FxRuby
- QTRuby
- WxRuby

The website from Arachno Ruby don't answer me these questions (or I have 
oversight this). :-)
