Making a form purely with flask-wtf

hi all,

i want to design a web form using purely using flask-wtf only, i dont want to use HTML

i want to use labels, text boxes, password fields (passwords must match and contain one number, capital special) and a submit button and then once they hit submit it sends it to a powershell command with the variables the user has entered in the text boxes and password fields

is this possible please

thanks,
