Integrate a Stripe Form into the shopify Store

Hi. I want to Integrate a Stripe Form into the shopify Store. [login to view URL] here you see the button 'Buy now' currently the button triggers the cart what i need if to push the stripe form below the button [login to view URL] this stripe form this form is very good, and the sources are available on github the goal here is that the user never leaves the product page click on buy now > push a form below the button > user fills out the form > the form gets replaced by a confirmation message once the order is made, communicate with shopify api to input the order on the product page the user will chose the product variant he wants + quantity, we will need to charge him for this exactly, and show this on the confirmation/order summary confirmation/order summary will also appear on the product page it should replace the form by the confirmation the user should stay on the product page from the beginning until the end at the end, all I'll need to do is to install the app, input my strip api keys, and maybe be able to add some custom css as i want to use this app on many stores i own
