I believe programming languages have few things in common with natural languages. Even though some experts in psychology claim that foreign language skills is a better indicator than math skills if someone will be good at learning programming languages or not.

At MIT some people tried to write code using natural language: http://news.mit.edu/2013/writing-programs-using-ordinary-lan...

Both programming languages and natural languages can be described in terms of Formal language theory and that's the most they have in common: they have words, grammar.
