john-doe There likely will never be a complete frontend for the gentoo package-managers (there are currently 3 choices). There is also little reason to make every option and action available via the gui. The main reason is there are very few users that would ever use most of them. Also there are several options that would not make sense for a gui as they are cli (command line interface) oriented.
The guis frontends are best used for browsing the available packages and versions, having the most common data about them ready at a click of the mouse, etc..
The fact that they also allow you to merge,unmerge and update packages is an added convienience. Certainly not the most important feature.
but if U 'hate' gtk...
Then install layman and add the gentoo-guis overlay, then install kuroo4. If you have any troubles with it, then re-read my earlier post about joining the gentoo-guis irc channel to ask for help, etc.. It is a "live" ebuild which means it downloads the latest source and compiles, installs it. It is nearly ready for regular release tarball and version. There alikely some quirks you will come across, so help out the maintainer and report any you come across that do not already have a bug filed.
[Edit] I see from another of your posts in a
different forum thread that you are trying kuroo already.
