I don't know about installing a visual captcha, but if you can get some help with the code a 'text captcha' is an easy thing to add. Heck even adding a visual captcha will require some programming skills, Basically it'd go like this:
On your form you add a new text field with a message "What color is red?". Obviously the visitor is expected to type 'red' as the reply. You make the question be whatever you want. Who was in the White House when Clinton was President. Five comes after what number (4 letters). Are you a spambot?
So now when the form is submitted you check that field first. If the answer is not exactly what you want then you can either just ignore everything or provide a page telling the visitor they missed an important field.
Anyway for someone familiar with coding a form page in general adding this detail shouldn't be a problem. Eventually you might get some spam, but so what: you simply change the question and answer and you're good to go again.
