Also, you can't connect the timer signal in the way that you hope, you 
need to do something like:

(in timer)
self.newQuery = newQuery
self.timer.timeout.connect(self.createQuery)

(in createQuery)
self.query=QtSql.QSqlQuery(self.newQuery)

Or:
(in timer)
self.timer.timeout.connect(lambda: self.createQuery(newQuery))
