Yes, I can and I have done it before, under time pressure. I was one of the original employees of k12.com, working as a Sun/Solaris sysadmin and late one night the "web team" had a next-day deadline to make a registration system work. There were press releases and print materials being released the next morning with addresses and registration forms that needed to work and their big bloated "stack" was not producing anything workable for any of them. I ftp'd over an old, personal copy of cgi-lib.pl and hacked up a little web page that dumped to a flat file and cc'd an email address with every registration. It took about 45 minutes and they used it for a year.
