Howdy. If I understand correctly, it can't be done with Pivot Table (however, I have been known to be wrong - ask my wife).
You could set up a series of formulas. Assume Q1 data is in column B, Q2 in column C, Q3 in column D. Then put Yes in F2, No in F3, and Maybe in F4
In cell G2 put this formula:
=COUNTIF(B$2:B$6,$F2)
Then copy into the entire range (G2:I4)
