Two things.

(1) This is a question for qt-interest; this list is for issues
concerning the IDE itself, not the toolkit.

(2) If signal connections are the only references you have, there's no
concern -- QObjects (QPushButton is one, of course) disconnect
themselves from everything automatically on delete. If you have other
pointers hanging around, consider QPointer; this is Qt's smart pointer
class that automatically zeroes itself when its referent is deleted.
