I Need help creating a BOT that announces everytime an upload has been made

This could be done on the server in the back end. If it's HTTP upload it might be done in a script perhaps as a mod to the upload script. If it's FTP upload it would have to be done in the FTP service or there would have to be a script monitoring the upload folder for changes. A client side script might periodically check the folder for changes and emit a message when it does. It would have to log in to the server and do the check, probably as an FTP client.

The problem with server-side scripts is that your web service provider would probably block or disallow IRC connections. IRC bots are usually indications of malicious activity and your service provider would probably become alarmed at that kind of activity on his server. Email notification is probably more typical and your provider would be more likely to allow it as long as it didn't send email spam.

Client-side, you would need a loop that periodically checks your site for new files, when one appeared it would dispatch a message. Your IRC program is probably capable of handling this kind of task.

Not sure about trackers. This would take some HTML knowledge and ability to connect to the tracker and get the stats dump from it. I recommend coding these as two different bots.

Sounds like a great educational experience, you'll get to learn to code IRC client scripts and learn some HTML. I suggest breaking out the manual on your IRC client and learning it's scripting language.
