good morning, I would like to have an error mesage in GUI which shows up whatever error it finds in any part of the GUI.
Is it possible to doit and, in this case, HOW?

Yes. Wrap your code in a try catch block. Here is the snippet:
try
% Some code that might generate an error.
catch ME
errorMessage = sprintf('Error in function %s() at line %d.\n\nError Message:\n%s', ...
ME.stack(1).name, ME.stack(1).line, ME.message);
fprintf(1, '%s\n', errorMessage); % Print to command window.
uiwait(warndlg(errorMessage)); % Popup message alert to user.
end
