You might try a listbox arrangement like this: http://www.mathworks.com/matlabcentral/fileexchange/24224. It gives a good GUI framework for starting something like this.
You could fill the listbox with .xlsx files, then when the user clicks on one, it reads it in and plots the results in an axes. You don't have to use image files and display them. You could adapt it to xlsx files and plot them.

I would suggest using the uigetfile function and then using the load function by using a pushbutton.
Using GUIDE, make a pushbutton and go to the callback, then type
% This lets you navigate to the file that you want.
[filename, pathname]=uigetfile
Path=stract(pathname,filename)
YourFile=load(Path)
Basically, your data now has the string YourFile in a matrix from the .xslx file.

Thanks! I had no idea fileparts even exists or the trailing slash issue. That line definitely helps with writing my codes as well and it makes sense!
