Getting my program onto a WIX site

Hi.

I created a program.

I have the html to add to the wix site.
I have the css, javascript and 200 images to add.

It is a tool to change the colours of windows and doors.

How can I get my program onto my wix site?

How difficult is this?

Thanks in advance

J
