I am honestly bewildered by your thought process here.
If I am getting someone to build me an Android app and I don't know how to do it. Then I am not going to learn Java, SDK, tool chain, build process and buy a device just to show them how to do it. I am going to send them an email and tell them to change it and go back and forth until I am happy.
I don't think you got my point about the story. The pregrammer made an UI utility in few hours so Jobs could design the calculator the way he wanted. A prototype can be done in whatever you already know, so there is no need to learn anything outside your current skill set.
If you aren't able to produce that then probably your programming skills are not higher enough and hence you could say that you can't code (not that is a bad thing anyway)
