Embed a calendar and a php form in a simple pluck website

I am setting up a simple website using Pluck cms. There will be only 4 pages. I need: -on one page i need to embed a google calendar (calendar is ready). I have the code from the google calendar but i am not able to make it show on the page. -on a second page i want to add a php form (Generated by phpFormGenerator. Form is ready) That's it. It's seems pretty easy. I just don't know much about codes. Thanks
