Hi, Heaven Eve, and welcome to chatbots.org! Shall we call you Heaven? Or Eve? Or have you another name (such as your first name) that you want to have us call you?
The only problem with using Program O to build a chatbot in Windows, is that, being written in PHP, it almost requires the use of a web server of some sort, not to mention having a database server, as well; unless you want to run your chatbot from the command line, which would further require some substantial editing of the chatbot script. I’m not saying it can’t be done (I run it on my computer, but I have a running web server and a MySQL database server, as well), it’s just a lot of work to get it to run on a single computer.
There are a couple of C++ based AIML interpreters available that can be compiled (or already have been) into a GUI application for use in a Windows environment, if I’m not mistaken, including Gary Dubuque’s Program N, CyN, and RebeccaAIML. Take a look at http://www.alicebot.org/downloads/programs.html to get an idea of some possible solutions. That page is a bit out of date, but it still provides some useful information.
