He said "free".

Here are some suggestions:

"octave" (http://www.octave.org or 
http://www.gnu.org/software/octave) does all kinds of neat 
mathematical processing, including FFT.

Most circuit simulators have some kind of Fourier transform.  Some, 
line "gnucap" (http://www.gnu.org/software/gnucap) give you source.  
Take the file "m_fft.cc" and wrap it however you want.

The GNU Scientific Library (http://sources.redhat.com/gsl/ or 
http://www.gnu.org/software/gsl/) has linkable code for lots of 
numeric algorithms, including FFT.

If you really want a spreadsheet, try "gnumeric" 
(http://www.gnu.org/software/gnumeric/gnumeric.html).  Like most 
spreadsheets, it does Fourier analysis and lots of other stuff.  You 
can write extensions in Python.

If this isn't enough, look in http://ibiblio.org/pub/Linux/apps/ , 
particularly in the circuits and math directories off of there.
