DHCP & DNS Servers for OS X (Alternatives to DHCPD & BIND)

I've spent some time searching this topic via Google and have come up empty.

I have an '06 Mac Mini that I use as a server. I run OS X 10.6.4 (not server) currently and would like to have it serve up DHCP addresses as well as host my local DNS.

Ideally I would like to run nice GUI based apps and not dhcpd & bind. (i.e.: On Windows hanewin makes nice simple GUI tools for this purpose)

Do such bits of software exist or am I restricted to dhcpd & bind?

Any and all recommendations would be appriciated.

As I continue my research I have discovered BIND is installed on all Macs. There is a nice BIND configuration tool available for non-server verions of OS X. It's called iDNS.

Now - all I need is a similar tool for DHCP and I'm set.
