Designer for GLCD?

Can anyone recommend (if there is such a thing) as a design tool to help with GLCD layouts? Or is it just a case of old-school pixel-bashing in traditional paint tools?

You can try FASTLCD by Bojan I. - MICRODESIGN. You can download version 1.20 here http://rs-rey.pagesperso-orange.fr/electronic_ressources/Ressources/8051/GraphicLCD/fastlcd.zip

Or if you only need a maximum of 8 high level objects (buttons, labels, etc...) on screen, you can try http://www.visualglcd.com/
