Some things are not offered by the CLI where GUIs can provide value-add, e.g. audio + video bitrate calculations for 2pass encoding targeting particular file sizes, stream selection dropdowns when you want to burn in one of several subtitle tracks etc.
Consider WebM4Retards[0]. It provides a simple UI for some avisynth filters + ffmpeg while also allowing you to export the avs scripts and ffmpeg command line if you want to run them manually. It fills a particular niche between simple transcoding/muxing and non-linear video editors plus encoding pipelines.
Additionally GUIs can help with tasks that you execute infrequently enough that you don't manage to memorize the myriad of command line options. MeGUI is convenient when adding chapter information to a video which I do once in a blue moon. In principle I could do this with text files and mkvtools, but it's just faster to use the GUI than reading the manual (again).
