simple way for owner to edit one part of one page

[unwashed potato!]

customer would like to be able to quickly add a couple of paragraphs and heading once a week to a latest news style page. it needs to be very basic just to allow her to say the date/heading, then paste the text and done.

currently the file is being sent to me then i have to manually update. but this isn't so good as she's relying on my having the time and being in a place to update the file when it needs to be done asap.

any ideas of what to use?

bit much for wordpress as it's such a small amount that needs to be edited. i've seen suggestions on here before for what i need buy sadly i've forgotten them
