Would like to make a little pond in the garden with three or four
goldfish,
and a couple of waterlilies? Would this be very difficult? ( or very
expensive?)

Two pieces of advice:
1. Go for the largest pond you can afford and accommodate - small ponds
are more difficult to regulate because the small volume of water is more
rapidly affected by a changing environment, e.g. may freeze solid in
winter.
2. When you buy the fish, check what their fully-grown size will be and
that the pond can properly accommodate that size.
