If you are buying boe bot just use BASIC.
A programming language is only complicated when the syntax is difficult to master (such as assembly). However, the concepts are what you really need to know to program. Once you learn a concept in one programming language, you can easily do that concept in any other programming language. Concepts include definitions, variables, functions, arrays, trees, pointers, etc.
The reason I say BASIC is easiest is because the syntax is the easiest. But it lacks in features and function, not allowing you to apply more advanced concepts in your programs.
