Is there anyway to turn a momentary on push switch into a SPST?.. so
that if you push it once it keeps the circuit on.. then if you push the
same button again the circuit turns off. Any help would be appreciated.

Not easily. What are you controlling, and from what kind of power
supply? Is this a homework question?

no it's not homework, it's just curiosity.. i'm basically wanting an LED
light to turn on and off by touching the button.. just a small part of a
larger system that i'm working on. The test circuit will receive 3VDC

OK, build Jim Thompson's flip-flop circuit, and make sure the switch is
debounced.

Is your pushbutton SPDT by any chance? If so, a much simpler solution can
be made using an R-S flip-flop made from two NAND or NOR gates.
