Can't figure things out with Form making in Word

For the life of me, this senior citizen has problems with using Word and
making forms. Is there a program that is easier, and then allows me to save
it as a Word document. I can't figure out how to make a form header, like
"The Company" then get out of that mode and make boxes with writing inside
of it, like "from:" and "to:" I have FormFlow and JetForm, and liked them a
lot, but they are not in business anymore, and as far as I know, can't save
into Word? Any help is appreciated...........Peter
