Check out this page, 
http://developer.kde.org/documentation/tutorials/kdialog/t1.html

It is all about kdialog. I use it for quite a bit, I really like it.
I'm not reusing the same zip file over and over again, but in order to copy 
files and compress them I essentially have to append the files to a zip.
I need to do it one file at a time so I can have dcop report to kdialog that a 
progress has been made. If you want, I'll send you my script so you can look 
over it. I've found a few problems with it, but for the most part, it works 
really good.
