It's pretty much like that. Debug builds are to be used with a debugger, like 
the GDB in QtCreator to debug your application in the testing phase. This 
produces larger binaries with lots of debug symbols to help you find bugs in 
your code. If you think your app is RTM :) then you simply compile it in 
release mode, with a smaller size and without debug symbols.
Note however: when building in debug mode, you have to provide your 
environment with the appropriate debug build of Qt as well (for example 
QtCore4.dll is the release version and QtCore4d.dll is the debug version [note 
the d before the dot]) On Windows platforms, using the Qt SDK installer, you 
don't get the debug version of Qt; keep that in mind! HTH
