It depends on your use case.

QDir::mkdir should be the right thing if you want a Qt-only application or 
only need to manipulate the local file system.

KIO::mkdir is the right choice for KDE-integrated file managers (or similar) 
which need to be able to create directories on remote and special file 
systems.

KIO::NetAccess::mkdir is the synchronous counterpart of KIO::mkdir. See the 
detailed class description of KIO::NetAccess (at [1]) for details.

KStandardDirs::makeDir is something you hardly ever have to use. It operates 
only on the KStandardDirs areas in the file system, which is mostly use as a 
_file_ storage (and I for one never had to manually create directories there, 
this is usually done inside QFile and friends).
