Free utility
WineBottler can "bottle" Windows programs into separate application bundles that run as standalone Mac apps. Just download a Windows Setup executable, then open it the WineBottler app. You can install them in a fake C: drive and run them from there easily. However, if you want to create a standalone application bundle WineBottler will create a separate bundle with Wine included inside.
I tried one of my favorites I have been missing on Mac,
MediaCoder. Installation works great and it runs without problem. According to MediaCodersite it should work under with Wine under Linux and
Mac with Darwine so I guess WineBottler got just it's
own Wine build.
