I guess the simplest, but most expensive solution would be to use three
cable converters and switch between them.

The least expensive, and least convienient solution would be to get a
remote which has channel up/down buttons and remote these to large
buttons. It might, however, take her an excessive amount of time to
step from say channel 4 to channel 36.

Finding a cable box or TV with three "favorite" channel settings is
probably unlikely, at least I've never seen one.

So.... I'd probably build a circuit which, after you press one button,
uses solid state switches to activate a hacked remote control
transmitter. Off the top of my head, I think it would require an
NE555 oscillator, a BCD counter (maybe a 7493), and an analog switch.
Probably have to toss in some odd gates.
