My stepbrother used to do that. After politely turning down about his third "simple" idea, I tried a different tack and asked him to draw the entire app on paper. After all, if it was so simple, it wouldn't take long to draw right? I insisted he include the appearance of validation messages, system generated emails and administration screens. He didn't ask for my help again, but to his credit he did paper prototype another idea and got a guy to code it.
