The first thing you need to do is learn a programming language. There are several programming languages out there, like C, VB, Java, Perl and tons of others. My personal recommendation would be to start with C++.

Once you learn a language, you need to get a compiler. The compiler translates what you type into code that the computer can understand and creates the executable file. Not all languages need compilers - those that don't are called interpreted languages. Java is an example of an interpreted language. There are different compilers for each language. You can download free ones from the internet, like the GNU C compiler (also called GCC). You can also load the Java programming tolls for free from http://java.sun.com/ and read some instructions on Java programming at http://java.sun.com/docs/books/tutorial/
