It's not fair to think they can learn how to really develop software in a few months. It sets them up for an unreasonable expectation. Can some people do it? Yeah sure. There are always going to be those few people that can pick it up and grasp it that quickly, but for most it's just not possible. I've met a number of people with 4 year degrees that can barely do it. If this were easy, then there wouldn't be a shortage of developer constantly. I am sure there are some jobs people with a couple months of experience can do adequately, but this is far from the norm.
