Need help to do an insert from other table in the new table just created by default ( like a trigger to fire after create table )

Hello all,

I need, after one specific table is created, with syncdb, to insert
in that new table some values from other table. Exactly I need to add
in a column of the new table all fields from other table. How can I do
this, I know that trigger can't fire after a create table event, what
else can I use?
