welcome to gimp-forum.net but first a question
Is this intended for a batch operation involving many images or is it just a one-click requirement for one image?
For one image (even for a batch) you might get someone to write you a script.
For lots of images, I might do lots of files one size at a time with the Gimp batch plugin BIMP.
edit: Inclined to recommend a command line application ImageMagick.
For a single file this works in windows
of course that would have to be wrapped in a batch file for lots of images.

Code:
magick filename.png -resize 128x128 -write filename_128.png ^ -resize 56x56 -write filename_56.png ^ -resize 28x28 filename_28.png
