Well, I'll be a monkey's behind...there really IS a way to get a readout on freqs from GoldWave.
Options>Controls>Device Control Properties>Graph>Spectrogram/Show Axis/Kaiser 7>OK
(Checking the Show Axis checkbox is what revealed the numerical range on the graph.)
Still not sure you could capture this info or print it out... but it certainly makes GW a lot more useful for a seat-of-the-pants (read: monkey's arse) analysis.
