No, this is called the "creator code signature" and is a unique series 
of exactly four characters that identifies your app to Apple. It was 
required in OS 9 and is still accepted in OS X, but I don't know if it 
is entirely necessary any more. To get a creator code signature, you 
need to go to Apple's web site and try different combinations until you 
find one that has not yet been used. Apple will then enter it into their 
database and your app will be the only one that can use it. Generally 
the creator code signature is marginally related to the name of your 
app. For example, I have registered "Casey's Solitaire" with a creator 
code of "cSOL".

If you have not registered a creator signature, the four question marks 
are the default and you should leave them there. If you do want to 
ensure a unique signature for your app, you can get one here:
