As far as I know, most slackware users are happy managing packages using CLI.
I know that there's slapt-get which has a GUI front-end.
A quick google tells that you need to install slapt-get first (command line manager)
and then install slapt-gui via slapt-get.
This is not a part of official Slackware release so I don't know how stable it is. I used it
some time ago for a few hours.
