This *calls* self.com(a) and assigns its *results* (which happens to be  
None) to the command option in your button. So your button does nothing.

To do what you want, use:

          self.a = Button(self.frame,text="button")
          self.a.pack()
          Checkbutton(self.frame,text="hello",variable=self.var,command=self.com).pack()

in __init__, then:

      def com(self):
          if self.var.get()==1:
              self.a.config(state=ENABLED)
          else:
              self.a.config(state=DISABLED)
