>>>You'll probably also need a de-bouncing (correct term?) circuit if you use a 4013.  
 
R-C will do it. 220k and .05uF  
 
R from V+ to 4013 input. C from 4013 input to ground. Momentary switch in parallel with C.  
 
A 4013 has fairly hefty drive so if the relay coil has a high enough resistance the transistor may not be needed.
