Completely lost, need to create a register thingy

I need some help. First of all, I would like to know if creating something like this is possible:

A simple page with the following things:

Account Name: [TEXT FIELD]
Account Pass: [TEXT FIELD]
E-mail: [TEXT FIELD]

Submit Button

Upon clicking submit a txt file would be created with the inputed info like this:

(Account Name),(Account Pass),(E-mail)

That file would be created in a specified folder on my computer. The page would also be run from a personal FTP server on my computer.

So, is this crazy thing possible?
Thanks in advance :slight_smile:
