I'm working on a new Ubuntu configuration to deploy for friends and family. One of the capabilities I wanted to add was simple remote webcam viewing. While webcam-server is old it met my requirements but it's a command-line application. To deploy webcam-server I had to make it more friendly which meant making a video device selection dialog for it. My current programming hammer is BASH shell scripting but to make a GUI I turned to utilities that can produce dialogs and provide feedback to command-line applications. There are many to choose from but for different environments I had to make custom versions of the script, select the dialoger with a script parameter, or try to select it dynamically. In the great tradition of overdesign I chose the latter.
