oh... your idea seems to be promising in case of server client model. so in case if i use html, I will also have to use CGI, don't I? and Yes I have program specification. I need to give users 2-3 options, and he will choose and accordingly my program will choose the scripts to run. I have created a demo using perl-tk and in which i have used button . user will press the button and program will run specific perl scripts. i have used perl-tk in it. So can you elaborate how HTML could be more useful or better?
