wicd is being ported to python3, slowly, but it appears, surely. Or perhaps it's happening quickly, considering there seems to be only one person working on it.
See:
Dev1Galaxy thread https://dev1galaxy.org/viewtopic.php?pid=52211
Github https://github.com/hanaguro/wicd
Launchpad https://git.launchpad.net/~hanaguro/wicd/
Hopefully some idle but able wizards of HN can help the project along. Otherwise, I am very eager to see it in the Linux repos once again, some day.
