With winpcap, you can capture wireless traffic, you just have to specify the 
correct interface to capture on. However, you cannot modify traffic with 
winpcap, as it only provides read-only packets.

I have used "netfilter" before to drop packets and I believe you can also 
modify packets with it. It's open source and is written in c++.

What header are you trying to modify and at what level (ip, tcp, etc)?
