Newbie question - GUI database editor in 15-minute blog screencast?

Hello all,

Pardon the newbie question but I was wondering what program is used to
edit the database tables & fields in the screencast showing how to
build a blog in 15 minutes on the RoR Web site. The program first
shows up around 2:25 in the video.

& my next question is, is there a Windows version available? It would
be nice to have a GUI editor like that...

Thanks in advance for your help!

That's textmate in the screencast. There've been lots of blogs titled
"Textmate for Windows?", google for them (I think talking about
RadRails/Aptana and e-editor, mostly)
