[Gimp-user] Blur / darken a selection as a new layer?

["S.Bob" <sbob quadratum-braccas com>]

Hi All;


I wan to select a rectangle on an image, and do the following:

- make the selection a new layer so I can easily move it around and 
resize it if needed

- add a border to the selection

- blur / darken the background of the selection

- add text to the selection


I know I can add the text as a new layer, not sure how to properly do 
the other items, thoughts?


Thanks in advance
