If you’re willing to do custom coding, almost anything is possible. If it can be done in PHP and JavaScript, it can be done in WP. A related question is “Are there available plugins to do this?” There are thousands of plugins available to do different things, yet when it comes to a particular need, there often seems to be a lack of availability. You’ll have better luck finding something by looking for specific functionality of each element instead of one all encompassing plugin. However, such an approach could still involve some custom work to tie things together.

WP already has its own login system. Points can be tracked by having jQuery send Ajax requests on certain click events that logs points for the current user server side. Points can be stored in user meta.
