Now you can start using Apache and Co. Firstly you should try »Status« on the left navigation to make sure everything works fine.
After testing you may take a look at the examples below the test link.
If you want to start programming PHP or Perl (or whatever ;) please take a look at the XAMPP manual first and get more information about your XAMPP installation.
