In general, replacing a rubber hose is a very easy repair. But just as in
doing anything for the first time, it's always possible to damage something
in the process and create a bigger problem than the one you were attempting
to fix. That's how we all learn.
I am afraid that "connects to something in the top..." is not a good enough
description to diagnose what you are talking about. How about posting a link
to a photograph?

As HT says we need more information.  On my 91 and 92 there are only two
hoses going to the heater core which  is about where you described.  I'll
take a look at my daughter's 97 when she comes home tonight and see if it
has four hoses.

If it IS the heater core is seems more likely that the core would be leaking
than the hoses so you might want to make certain that it's a hose leak.
Sometimes the hoses are difficult to remove and I've used a 3 foot pry bar
to get them off the heater core but I was replacing the core anyway.

It is just a guess, but you could be refering to the heater valve.  If that
is where the coolant is coming from, it may be the valve and not the hoses.
That repair would be fairly simple, and the parts cost is under $30 for
aftermarket parts.
