How Can I Place A Widget NOT In Sidebar

The title is pretty self explanatory :slight_smile:

I want to create a html/text widget in my widget area in the WP dashboard, then I want to be able to place the widget inside my body of my post. If possible I don't want hack my theme or functions.php file, simple would like to be able to "paste" the widget code into the body.

Is this realistic?

If so please tell.
If not please direct me.

Thank you.
