Thank you sir @Chris Warrick for your great suggestion, even though I
really got overwhelmed by the things that I need to study to get this
project done. I'm really new to programming  so I havent heard or even
tried DJANGO, but on your suggestion, if thats what I need to get my
project done, that would I do. It would really take alot of time for me to
finish this project, but thank you man, I really appreciate your help
