Here is some code registering the stuff programmatically. Frank already told 
you the correct solution for doing this via the ZMI.

from zope.app import intid
from zope.app.catalog import catalog
from zope.app.component import hooks
from zope.security.proxy import removeSecurityProxy
from zc.catalog import index, catalogindex

        # Get the local site manager
        sm = removeSecurityProxy(self.context.getSiteManager())

        # Create an intid utility
        if 'ids' not in sm['default']:
            ids = intid.IntIds()
            sm['default']['ids' ] = ids
            sm.registerUtility(ids, intid.interfaces.IIntIds)

        # Create a catalog
        ctlg = catalog.Catalog()
        sm['default'][name] = ctlg
        sm.registerUtility(ctlg, zope.app.catalog.interfaces.ICatalog,

        # Set the site, so that the indices don't go crazy
        originalSite = hooks.getSite()

        # Add indices
        ctlg['name'] = catalogindex.ValueIndex('name', IContained)
        ctlg['interfaces'] = InterfacesIndex()

        # Reset the site
