I don't know, can you use MySQL and PHP well? :p
If you're asking if those two technologies are able to accommodate this use case, then yes, they are more than able to do so. Designing and interacting with a database, however, is nothing you can learn to do well in a day or two (maybe not even a week, TBH). Before you start, for example, I would find a good article or two about security (SQL injections, data sanitizing/validation, etc. etc.) as well as a couple about database normalization techniques.
And of course, once you design your DB schema, feel free to post all of it here for critique/suggestions.
EDIT: Also, welcome to PHPBuilder!
