Getting ideas but I don't know what coding languages I would need to implement them...?

The best language for implamenting code on a website is java. However it is not a good idea to learn this as your first language as it forces object orientation. Python 3 would be an ideal language to learn as it is the easiest to learn. There is a wiki books page for the 'Think Python' pdf which is free. it will take you through the basics to lower intemediate skills such as using cles and databases. I would not recomend C or C++ as these are not garbage colected and thus you will ave to learn memory management which can be a waste of time in the early stages of learning to programme.
