Depending on the latest improvements to the fink distro, you may need to re-build qt3. When kde launches, turn off icons on desktop in Settings->Control Center->Desktop->Behavior. Binaries are still catching up, so source installs are the way to go.
To be able to access the windows buttons, etc you may need to select Minimize from the X11 Window menu to "remove" the transparent icons layer until you make the Desktop Behavior settings.
