No. A Cisco WGB device does not support multiple VLANs in it. A 1100 AP, however, that acts in WBG mode can support multiple VLANs in it but with these restrictions:
The VLANs must be assigned on both the root AP and WGB sides.
The WGB must be connected to a dot1Q-capable switch.
The Infrastructure SSID must be mapped to the native VLAN on root and the WGB.
The WGB associates on the Infrastructure SSID.
With this configuration, it is possible to associate WGB (WGB BVI interface) as a Native VLAN and have wired clients configured behind a dot1q switch associated to different (non-Native) VLANs.
