You might want to try upgrading to Wine 1.1.5. Lots of things have changed since 1.0. If that doesn't help, there is a comment in http://appdb.winehq.org/objectManager.php?sClass=version&iId=900 that indicates one person, at least, was able to get it to work by copying all the Quickbooks Pro files from a Windows installation and adding the Intuit registry keys to Wine's registry. This was for a very old version of Wine (2 years ago), so it may no longer work, but it could be worth a try if all else fails.
