I'm often reluctant to jump at assuming my answers are sufficient when people mention that they're working on a GUI. If it turns out they need help with appdesigner or something, I'm not going to be much help since appdesigner is completely broken on my system.

Have you looked at imcrop()? Imcrop has an interactive mode and will output the selected RECT parameter when the appropriate syntax is used.
[cropped1 rect] = imcrop(thispict);
You can then call imcrop using that parameter
[cropped2] = imcrop(thatpict,rect);
To display the images, you could do that any number of ways.
You could use subplots or tiledlayout
subplot(1,2,1); imshow(cropped1)
subplot(1,2,2); imshow(cropped2)
or you could use montage:
montage({cropped1,cropped2})
or since they're the same size, you can just concatenate them and show them as one
imshow(cat(2,cropped1,cropped2))

I don't see anything obviously wrong from the picture. I'd have to be able to run the code and see the particular images to troubleshoot further.
