No, a wildcard in the zone will apply to any XXX.my_domain.com names that
aren't already in the zone.  It doesn't apply to my_domain.com itself.

If you want an address for the domain name itself, just create an A record
for it:

my_domain.com. IN A 1.2.3.4

It's just like any other record.  The RFC's on DNS don't say anything
special about this, since there's nothing special to say.

You didn't have any problem entering the SOA, NS, or MX records for
my_domain.com, did you?  Why do you think the A record should be any
different?
