Here are the packages I installed on my laptop with XFCE in order to run kmymoney2.
From Slackware 11.0 directory (
http://packages.slackware.it/browse.php?q=11.0)
Sub-directory slackware/kde: install kdelibs-3.5.4-i486-1
Sub-directory patches/packages: install qt-3.3.7-i486-1_slack11.0
I haven't yet installed ksudoku but it worked on my Slack 10.2 (of course with older versions of kdelibs and qt).
I don't know of a package that contains only kedit.
