I would add, this task you are trying to do is an advanced DSP topic. What you're looking for is a channelizer and this is optimally implemented using a polyphase filter bank. If you need a good reference on this, fred harris' book on Multirate Signal Processing for Comms Systems is a good.
http://www.amazon.com/Multirate-Signal-Processing-Communication-Systems/dp/0131465112 GNU Radio has channelizers built-in, but I've not used them yet, so I don't know how far they take you into this kind of task.
