Your prayers have been answered…
Begin by designing your form as normal inside InDesign. When you are ready to create the form fields, I recommend that you create a layer for the form buttons.
Next, draw empty frames (no formatting) wherever you would like text fields to be in your layout. After creating all of your text fields, convert each of them into a button. It is not necessary to give them any attributes like actions or appearances.
