[TxMt] tm_dialog -- outside of TextMate?

This isn't really directly related to TextMate at all, but... :) I've been doing some automation work to help make me all the more efficient in various ways. That's generally involving writing up scripts glued to various places-- and I've recently sort of wanted something like tm_dialog to integrate with them, entirely outside of TextMate. I mean, I use tm_dialog with a couple custom bundles for certain purposes but I don't really "live" in TextMate so much.

Anyone know if there's a way to poke tm_dialog into just doing its thing /outside/ of TextMate? Or, something else out there which fulfills a similar use? I saw CocoaDialogs, but what I loved about tm_dialog was that it could run custom nib's.

Anyhoo. Sorry for the OT post. =)
