Easy to use, portable, sound edition program?

[Stratos 3,188]

I need a easy to use portable program that can mix two sound samples. What I want, is to mix a short speech with some background noise in order to produce a AFAC sound file. Would be amazing If I can drag the two samples and then save the new file, as easy as possible.

Any recommendation?

I have used this software before and it's free and it will do the job.
