Welcome! Technically you don't *need* to install MacPorts if all you want is
Cairo. You could build it and it's dependencies from source. But using MacPorts
is indeed an easy way to get the job done.

You are correct; there is no GUI app called MacPorts. MacPorts is the command
line program /opt/local/bin/port.
The installer should have set up your PATH so that you can run it by just
typing "port" instead of that full path.
From your output above, I see you inadvertently entered MacPorts shell mode,
indicated by the ">" prompt, by running "port" with no arguments. As it says,
to exit that mode, type "quit" to get back to your normal shell's "$" prompt.
At your normal shell "$" prompt, you can run "sudo port install cairo".
