I've often wanted the same thing - I just cooked up a compctl that _almost_
works:

setopt interactive_comments

listjobs() {
jobs > /tmp/._zshjobcomp.$$ 2>&1
set -A reply
OIFS="$IFS"
IFS='
'
reply=( $(sed -e '{
s/.\(....\).............\(.*\)/\1 # \2/g
s/\]//g
s/  */ /g
}' /tmp/._zshjobcomp.$$) )
IFS="$OIFS"
}

compctl -P % -K listjobs fg

The only problem is that zsh is escaping the spaces & #'s that result from 
the completion, which looks really ugly.  Also, I don't really want 
interactive_comments set all the time - just for this completion, but I 
haven't thought of any way to do this (yet:)

Any improvements?  I suspect that the sed bit could be replaced by some neato
zsh internal parameter mangling stuff, but I confess I am not terribly handy
with most of the zsh-specific parameter expansion/substitution features.
