I spoke to Allen at Roland US and I'll be able to order the parts directly from them. The info is as follows:

The data wheel (Roland calls it an alpha wheel...it's used on a lot of their products): DR KNOB part #22485303

The small knobs: JR KNOB part #03565234 (quantity: 3)

The total (with tax and shipping via regular mail) comes to 22.89.

You can order directly over the phone, or send check\money order to:

Roland Corporation
PO Box 910921
Los Angeles, CA 90091-0921

Of course, GW-7 users in other locales will have to order from their local Roland support centers.
