Got a couple of questions for the gurus out there.
I'm looking for a (relatively) simple Paintbrush-like program so I can do some basic editing to send a Valentine to a friend(I know it was a month ago, but I'm in Japan, and they've got this thing called White Day here, so just trust me on it

). It's really basic stuff -- just some copy and pasting and adding some text, really -- so I don't need anything too sophisticated.
At some point, though, I'd like to give The GIMP a go, but I'm a bit intimidated by all things Unix (aside from OS X, of course). I'm running Panther, so does the inclusion of X11 make installing/using the GIMP any easier?
Thanks in advance,
Mike
