Some time ago (about 2 years ago now), Codeweavers developped winesetuptk, a configuration tool for Wine. It is now listed with other Wine related files on sf.net.
The problem is that the tool hasn't really followed Wine development (for example, removal of $VAR-style variables from config file), and some users experience problems because of that. It'd be better to not list it on our download page because of its staleness.
OTOH, I know that Mike et al.'s winecfg is not ready yet for prime-time use. Still, having a working, commented text config file to work with rather than an obsolete GUI tool is preferable IMHO. So I'd recommend the removal (or hiding) of it if nobody steps up to update it to current Wine practices.
