I have just finished and posted to the turbobraille website a simple cocoa front end to turbobraille. This program will ask you for a text file to translate and then let you save the resulting braille file. In feature versions you will be able to select the grade of braille as well as other options.
Please not that you must have turbobraille installed before installing this application. You can find this GUI at the turbobraille website http://w3.wmcnet.org/braille/tbrl/ Greg Kearney
