This is probably not that complicated (I hope?!?) but I need a PC
program that would just tell a PC soundcard to generate a standard
CTCSS tone (example 107.2 Hz) sinewave that could be fed into an older
FM amateur transceiver. I don't want to find/buy/build a CTCSS module
for it, and will have a PC handy. I imagine a WAV file could be
created, but if there is some kind of software (perhaps a "function
generator" program) that would be ideal, particularly if you could just
give it the frequency in Hz or something like that, and get a steady
sine wave out of the sound card.

Try http://www.goldwave.com/ for a Windows-based solution
(fully-functional demo version can be downloaded).

For Linux, try http://audacity.sourceforge.net/ (free)

Both of these should be able to generate, and then play, a WAV file
having a sinusoid of almost any desired frequency within the PC's
audio bandwidth. I used Audacity to generate precise sinewaves to be
used when calibrating an FM modulation meter via the Bessel-function
null method.
