Dude, this looks exactly like Homesite!

Functions much the same way too, but this is totally free. Can't get it to simultaniously open a list of files, as I do in Homesite, I'm forced to double-click each one.

Norton AntiVirus Auto-Protect reports JS.WindowBomb among the install files, but I suspect it's actually detecting code supplied as one of the canned (and somewhat dated) JavaScripts with the program designed to insert into your web pages.

The web site has some encouraging hints at a 2006 Beta version of this app.
