Answer
Mixing these two compounds will not result in a buffer.
Work Step by Step
$$HCl(aq) + NaOH(aq) \longrightarrow H_2O(l) + NaCl(aq)$$
Since $HCl$ and $NaOH$ are both strong electrolytes, the resulting salt is neither acidic or basic. Thus, there is no conjugate weak acid-base pair, and it does not act as a buffer.
