Sure, I'll bite:

#!/usr/bin/perl -w
use strict;
use CGI qw(header cookie);
if (cookie("val")) {
  print header(),"Your cookie is still set";
}
elsif (param("val")) {
  print header(-cookie=>cookie(
          -name =>'val',
          -value=>param("val"),
          -expires=>'+1M')),"Success! Your cookie should be set";
}
else {
  print header(),q(<html><body><form method="POST" action=""><input ty
+pe="text" name="val"><input type="submit" value="Click here"></form><
+/body></html>);
}

Steps: check for the cookie. If present, display still set page. If not, check for a parameter. If present, set the cookie and display success page. If not, display form. I haven't tested the above code, but you should be able to understand what the process entails. I used CGI for all the nasty work. Please click that link and read EVERYTHING. Then check out Ovid's CGI Programming with Perl course.

Hope this helps.
