I think you'd be better off just getting a book on the FFT to start with. Implementing it in Mathematica is trivial - indeed the built in functions Fourier[] and InverseFourier[], and the FourierTransform package probably do what you want. A good introduction to the FFT and what it can do is: "The FFT, Fundamentals and Concepts" by Robert W.
