In addition to FFTW, there's also http://cr.yp.to/djbfft.html which
doesn't appear to have any restrictions.  It appears to be for very fast
computation of powers of two FFTs.  It's in very nasty C, though.  I have
here a package fft_pack with Glassman's algorithm for arbitrary N, but I
can't seem to track its provenance.  If speed isn't an issue, it's quite
convenient.  Numerical Recipes in Fortran (etc) has source and discussion
of various FFT situations.
