Adding a PHP Query

Hello to you all, im looking into adding a php query onto a page generated by the wordpress software.

Is there anyway i can do this by adding the code into the page box from the admin system ?

It will only be on 1 page. The page is here http://www.fleetwood-fishing-industry.co.uk/fleetwood-trawlers/ you will see a list of trawlers on that page. I have made thos links manually but i now have the query but cannot get the php code to work on the page.

All help will be greatfully recieved.
