Bluetooth modules are available that would suit your needs for short ranges, like the same room, or a room away. But it would require relatively sophisticated knowledge of electronics to create a controller circuit that could transmit those analog signals and decent software to do anything with them. Unless you are familiar with micro controllers and building your own circuits on perfboard you're not going to get very far. Look for commercial modules (Try searching Google for bluetooth data acquisition) or find someone that could manufacture a module which does what you want. Even with a modest budget it shouldn't be too difficult to put something together assuming you could find someone to do the work cheaply.
