learning programming in one day

I have an opportunity to propose a one-day conference tutorial on the 
basics of programming (very likely using Perl as a basis).  Am I nuts 
for trying this?

The audience will be software testing professionals, with a good level 
of computer literacy, but probably little or no programming experience. 
        There is a general desire among many testers to learn how to 
program so they can automate their tests.  I can't hope to make them 
programming wizards by the end of one day.  I'm thinking I could 
introduce them to the basics so they'd be more motivated and able to 
learn more from a book or a longer course.

Alternately, I could specify that participants already know at least one 
programming language, and I could focus on teaching Perl.  I already do 
a tutorial that does this to some extent, though I currently focus more 
on testing techniques than systematically teaching Perl.

Any feedback on this before I put together a proposal?
