I installed a regular electrical box at my front door, ran 14 ga. romex from
this box to the doorbell transformer, then got a nice brass blank wall
plate, drilled a hole in this plate, then installed a 120V momentary push
switch in the plate. Then wired this to switch on the transformer when the
button is pressed. Then connected the two wires which were going to the old
button so the doorbell would ring as soon as it receives power from the
transformer.

Congratulations. You've just made a potentially lethal accident waiting to
happen. And somehow I suspect your insurance won't pay if someone dies.
I would STRONGLY suggest you do one of 2 things.
1. Rewire that doorbell to it's original configuration.
or
2. Put a GFCI into the circuit

Either way I think would be safe. Option 1 of course would be cheaper, but
if you insist on saving the few pennies worth of electricity, then option
2 would work. And it would be a rather interesting experiment to see how
often the GFCI trips.
