Soft wrap lines to a column (not to editor window)

Is there a way to make soft wraps work only for a specific column (column 80, for example), independently of the size of the current editor window?

The appearance would be like using regular soft wraps if the window was as large as the 80-column text and like (almost) hard wrap if the editor window is narrower.

For example, consider the following text: "Sed ut perspiciatis, unde omnis iste natus error sit voluptatem accusantium doloremque laudantium, totam rem aperiam eaque ipsa".

No wrap at all:

Sed ut perspiciatis, unde omnis iste natus error sit voluptatem accusantium doloremque laudantium, totam rem aperiam eaque ipsa

Current appearance I get so far for wide windows:

|<--                                                                      column 80 -->|
Sed ut perspiciatis, unde omnis iste natus error sit voluptatem accusantium doloremque laudantium, totam rem aperiam eaque ipsa

Current appearance for "right sized" windows: 

|<--                                                                      column 80 -->|
Sed ut perspiciatis, unde omnis iste natus error sit voluptatem accusantium doloremque
    laudantium, totam rem aperiam eaque ipsa

Current appearance for narrow windows (say 60 columns of text):

|<--                                                  column 60 -->|     column 80 -->|
Sed ut perspiciatis, unde omnis iste natus error sit voluptatem
   accusantium doloremque laudantium, totam rem aperiam eaque ipsa

I wish for the 80-column look no matter the width of the text window. :-)

I'm using Texify, so I have long paragraphs...
