Don't think that is possible unless your wireless is on a deprecate subnet than your wired. If so, you would create acl's on the AP, but can be tricky. I never heard of anyone wanting to do that since you still have to login and when I troubleshoot, I'm always on wireless.
in wireless we always give IP on BVI and that is the interface through which we get the admin access to wireless device..
It is possible to give differnt IP on radio and ethernet interface but then how wireless will work.. as its a layer 2 device and different network IP will not be able to commute and there will be no traffic between wireless to data network side then..
