Candidate database

I need a very simple web application for managing job applicants. I receive many applications and I can manage these using opencats, but what I need is a system for identifying suitable candidates based on skill set. I currently do this in Excel, but I want to simplify this so that candidates will fill up by themselves. So the system will consist of a single page front end and two pages of backend. The frontend will be used by candidates to register their details: First name, last name, years of experience, email, phone number, location, authorisation to work in UK, availability, skills (Java, C#, C++, Perl, Python, Ruby on Rails, MySQL, Oracle, MSSQL, Sybase, etc (I will provide full list). Once the user submitted, we send a summary of what they have submitted to their email. In backend, the administrator can list all the candidates and then filter them based on skills required, location, availability. The second page is the edit page where the administration can edit a select candidate. As simple as that.
