After I had some issues with the planned subject of the next guide, I switched - for an example - to glade and would like to show, how you can do RAD with glade and gnu-smalltalk. It's really easy and fast, and you won't blow up your source-code with the complete gui-creation stuff. As an example I picked a password-generator, because I frequently have to set passwords for different user etc. in the company I work for.
