I think the OP knows that he isn't all that awesome at programming. As a friend, I don't go around pointing out to my friends weaknesses in their person they them selves are well aware of. In this situation the friend could have said something like "Oh, that's a good idea that you passed on that job, you are week in that area, and they were probably looking to hire you as a sacrificial lamb." A statement like that shows that a person is your real friend. They are acknowledging your weaknesses, but with the goal of helping you in the end of the day, not the company.
