You are probably ok without a comercial license. It depends on how heavily
you borrow directly from the gpl:ed source. The usual (unclear to me)
rules for what constitutes a "derived work" applies. 

If you start from the specification there should be no problem whatsoever. 
When in doubt contact the original author and/or your legal councel.
