This is what I would do, but you'd need some prerequisite software and information:
1. Get a genome for the simplest bacteria you can find.
2. You'd need molecular simulation software, specifically DNA and cells
After you've gotten this, I would strip out pieces of the genome using the genetic algorithm (oh the irony) and see if you can slim the genome down to a bare-bones replicating cellular machine.
After that, just a little trial and error and you could be making designer organisms.
(Sorry if you wanted something realistic. My brain doesn't work like that =)
