Laravel 4 send email from localhost to gmail

I am unable to send an email from my locally developed site..In my controller I have the following code :

public function store()
{
    $data = Input::all();

    Mail::send('contact.display',$data, function($message)
    {
        $message->to('giannhs905@gmail.com')->subject('Welcome!');
    });
}

And my view is below:

<h1>    
Subject : {{$data['subject']}}
</h1>   

<h1>
From : {{ $data['name'] }}
</h1>
<br/><br/>

{{ $data['comments'] }}

Initially I don't care about Inputs given in my form..I just want to send a dummy email to my account...

What am I doing wrong? Should I change some config. files..?
