Here is the problem with your question, and similarly with all the questions like "how can I learn to defend myself in a week" etc.
You can technically learn to throw a punch or kick very quickly, as it requires the least amount of complications. However, it doesn't mean that you will be capable of being good at striking after a few practice sessions.
That is what training is, learning a skill and then practicing the hell out of it. Learning how to apply a skill is what takes time, not really learning the skill itself.
