Pardon me for jumping in....
You can purchase the pass at any manned railroad station, as well as through various on-line services.
Please refer to the links about "passes" that I and Annika provided above if you need more detail.
There is a rail station at GVA airport, and you can buy a pass there.
As far as I know, you cannot buy them at a hotel.. You can, of course, ask your hotel.
