learning a new language may and may not be difficult.what do you think to be the simplest way to learn french?

It depends on what you mean when you say quickly: days, weeks, months? It is possible to learn French, or any other language fast, but that does not mean that you'll be able to master it in a few weeks, or even months. You can however achieve  'conversational fluency' in a matter of weeks or months, but it would be advisable to continue your study for a good number of years afterwords. A good start would be to get a french course that would enable you to be fluent, here is a promising one: http://frenchlanguagelessons.net
