How to Creating Database from a TQuery component?

Does anyone know how to create a database from a TQuery component for
Interbase?  I have tried the obvious "Create Database 'Gerald.GDB'", however
this doesn't work as it returns an error code 503 saying "Cannot Prepare
Schema/Database Statement"  Has anyone successfully created an SQL database
from within a Delphi component, and if so, how did you do it?
