Any programs out there that can set the IP numbers for a given connection with one click?

The problem is that I need to link to three different systems and need different IP's on each. One has working DHCP, one has a DHCP that misbehaves in some cases (always for me, although it works for most of us) and one with no DHCP at all.

What I'm looking for is something where I have three icons on the desktop, clicking them sets the 4 needed numbers. Whether it affects only the right connection or all of them doesn't matter.

Anyone seen such a program?
