Um, no. It's sent as a PIN message. Scroll into the header on the recipient BB and you'll see "Received using: peer-to-peer" which means it's a PIN message (not to mention that you have to supply the recipient's PIN when composing). Perhaps you meant "not a BBM message"?
Best bet is to use a Jivetalk on the BB and a suitable IM client on the PC as has already been mentioned.
