I do not know a lot concerning the circuit provided since i have yet to experiment with the IC but the above links may provide the info you are looking for; appears simple enough.
When used in a stereo mode i imagine you would use two of the ICs along with two DPST N.O momentary push button switches.
Although, it may be easier along with less expensive to locate 2 DPDT momentary pushbutton switches and only use half the switch etc...

You could also Google the IC part number where more circuit design may be available.

Maxim released another excellent stereo audio vol/balance IC that is very versatile, take a few minutes to review the data.
