You could use `auto-fill-mode'[1] which automatically wraps text
once it reaches a certain column (specified by the variable
`fill-column').  Alternately, if you merely want a visual
indication of whether you've typed beyond a certain column, take
a look at vvb-mode <URL:
http://www.geocities.com/gchen275/xemacs/>.  If you're using it
with Emacs (as opposed to XEmacs), you'll have to
(require 'lucid) first.

[1]  Enabled by typing M-x auto-fill-mode RET
