By using column-marker mode
(http://www.emacswiki.org/cgi-bin/wiki/column-marker.el) you can just
do:

(require 'column-marker)

 (defface column-marker-policy-face ...) # whatever you find nice
 (defvar column-marker-policy-face 'column-marker-policy-face)

(column-marker-create column-marker-policy column-marker-policy-face)

and then in programming modes' hooks, add:

 (column-marker-policy 80)

[I really use (column-marker-policy (setq fill-column 80)).]

It could be even easier by just using column-marker-{1,2,3}, but I
think these are best left for interactive use.
