Is it possible to have a generic object of a template class?

Example:

template <typename t> class CEvent
{ ...
};

class CEventlist
{ CEvent *event;
 ...
}

event in CEventlist shouldn't use a template parameter and CEventlist shouldn't be templated too.

Absolutely impossible. Template is not real class, actual class is created by compiler only when template is instantiated. For example, CEvent is not class, but CEvent<int> is class. CEvent* gives compiler error, and CEvent<int>* is OK.
You need to think in another direction. For example, template class may be derived from some non-template class (interface), and CEventlist contains pointers to base classes.
