monkey_matlab - try removing the uiwait and uiresume calls as I don't think that they are needed in this case.
The closereq is unexpected in the edit1_CreateFcn. Doesn't this generate an error message when you try to run your code? If you want to close the GUI when the user presses the OK button, then I would put this command into the pushbutton1_Callback or do
function pushbutton1_Callback(hObject, eventdata, handles)
close(handles.figure1);
assuming that figure1 is the name of your figure/GUI.
