2-dimensional Fourier Transform program

Can anyone recommend a 2-dimensional Fourier transform
routine, written in Fortran? The input data would be a real,
evenly spaced 2-D array, without data gaps. I've seen the
Numerical Recipes FFT routine, which needs the
data length to be a power of 2, or needs zero padding.
But, since computing power isn't a big limitation, and speed
doesn't matter too much either, I'm looking for a less
fussy, more easy-to-use program. Alternatively, a 1-D routine
which can use complex input-data would be fine.

Thanks,
Richard.
