Well, this is not trivial to do, which is why there is no implementation in DCMTK yet. You need to design a table structure that corresponds to the DICOM query model and implement both the storage and the query/retrieve interfaces. Altogether probably several thousand lines of source code, if you do reasonable error handling.
