Fillable form that is used to generate document

In my previous job, I had a word file that, when clicked, opened a form dialogue box. Depending on what was checked off or inputted into the form, a document was generated. I would like to create something similar for my current work. This would be a series of fields and checkboxes used to develop a Scope of Work document. Certain text lines and paragraphs would be added to the document based on the selections.

Does anyone know of any articles or guides to do this?
