CGI Scripts And HTML Forms

• Quite often, when we wish to write a simple GUI for a program, using a simple HTML interface (AKA "web-based GUI") could serve as quick method.
  
  
• HTML is a very simple language - if one sticks to functional pages, rather then to bells and whistles. Writing HTML forms is also quite simple.
  
  
• An HTML form could be used to insert all options for running a program. The program itself will be spawned by a CGI script running under a web server.
  
  
• Since a CGI program runs in a non-interactive manner, it is useful either for launching a short (= fast) program, or launching a long job at the background, and just stating the job was started, possibly giving the process number. A slightly more complicated 'job management' system could be developed on top of that.
