Well, I don't know how many SSIDs you want, and what VLANs you're using, so I'll assume a single SSID on the native VLAN. I also don't know what type of encryption you want, so I'll assume none for now. Finally, do you want the SSID to broadcast? I'll assume yes for testing purposes.
To create a broadcast SSID without encryption, perform the following configuration:
dot11 ssid ssid_name
To configure the Radio, perform the following configuration:
Finally, add an IP address on your BVI:
ip add x.x.x.x x.x.x.x
This should be good for testing purposes - let me know if it works. If you want encryption, more VLANs, etc... just post up and someone will be glad to help!
