You should be able to use the xlsread function to load the Excel file into Matlab. You can use the mean function and the standard deviation function to calculate those parameters.

Try this:
% Have user browse for a file, from a specified "starting folder."
% For convenience in browsing, set a starting folder from which to browse.
startingFolder = 'C:\Program Files\MATLAB';
if ~exist(startingFolder, 'dir')
% If that folder doesn't exist, just start in the current folder.
startingFolder = pwd;
end
% Get the name of the file that the user wants to use.
defaultFileName = fullfile(startingFolder, '*.xls*');
[baseFileName, folder] = uigetfile(defaultFileName, 'Select a workbook file');
if baseFileName == 0
% User clicked the Cancel button.
return;
end
fullFileName = fullfile(folder, baseFileName)
% Open Excel workbook:
[numbers, strings, raw] = xlsread(fullFileName)
% Extract column 1 (or whatever).
col1 = numbers(:, 1);
% Compute mean and standard deviation, or whatever
theMean = mean(col1);
stDev = std(col1);
If you want to, you can put that all into two separate button callbacks, but it's a little more complicated, so if you go that route, you'll need to study the FAQ: http://matlab.wikia.com/wiki/FAQ#How_can_I_share_data_between_callback_functions_in_my_GUI.28s.29.3F

Just use GUIDE to place a button on the GUI, then right click and say View Callback. It will throw you into the editor. Then you can write your code into that function. See the GUIDE tutorial for further instructions: http://blogs.mathworks.com/videos/category/gui-or-guide/
