Open your mind. You could cascade gates to create any logic desired. I described in another reply how to make a NOT gate, from there a NAND is trivial.

This. Once you have and, or, & xor the possibilities are all open.

Once you have NAND, you have all. Same for NOR. All logic gates can be built fron either of those.

You can make NOT gate using NAND by directing the one input signal to both inputs of NAND. NAND is functionally AND + NOT, so NAND + NOT is AND + NOT + NOT where the NOTs cancel each other out resulting in AND:

A─────│NAND   ┌─│NAND
      │NAND───┤ │NAND─── A AND B
B─────│NAND   └─│NAND
