Python will be the easiest. Java somewhere in the middle. C++ will be the hardest. I would suggest starting with Python. Once you're comfortable with Python, you should learn Java. Unless you have a specific need, the next language could be C++, but equally could be Go, or C, or Rust, or Javascript, or Erlang, or Scala, or OCaml, or Haskell, or something else. C++ is big and complex. I wouldn't recommend it as a starting point -- once you've got a few other perspectives under your belt, tackling C++ will be more productive.
