Tag google analytic. Please

Add Google analytic tag

Good morning people. I would like some help to insert a TAG and account for google my visits.

I need to insert this tag:
<button type = “button” onclick = “_ gaq.push ([‘_ TrackEvent’, ‘budget’, ‘click’ ‘button’]);” title = “Click here” alt = “submit”> Send! </ button> </ p>

Along the SEND button that corresponds to my BUDGET form, where I use the contact form 7.

In addition to sending to my email must send to google compute.

There’s a possibility?
