adding GUI for this console app

Your program is very good. I really appreciate that.

Also, I want to add GUI using PureBasic. I did not change anything in your source codes, rather, I just used the command line arguments and output of your program to interface. And it was a success.

However, I was able to do that in just a short period of time, but I will complete the necessary GUI rendering for all the features that you created in the original console program.

Hoping that you will accept this pull request and we will continue working together. Thanks.

Attached here is the picture of the added GUI. For users, they always like to interact in this way.
