Develop a simple application that displays the corresponding Urdu character (see attachment) in a window similar to the Mac volume display (see attachment) when the key is hit. The actual character produced should be the roman character. Application must be in the menu bar of Mac, and have the option to launch at start up. Please keep prices low, application will be open source and free, used to help people learn the characters.
Would prefer version for Linux as well, but will discuss.
