Designing “Pears to Pears”

So Dmitry came up with the idea that we modify a game called “Apples to Apples”. The new version would be called “Pears to Pears”. Any ideas on how the GUI should look for it, so we can get started designing it? Also, does anyone have ideas on how we would implement it. So far, I understand we would need a client/server type of program, but what else do you guys think we would need?
