Simple program with a formula

Hello everyone! Could anyone help me with a program using GUI: I have this simple formula x+y=z. I have an "edit text" for each x,y and z and I want the user to be able to write a number in "x" and a number in "y" and the result to come up in the "edit text" for z. Any help with the code?? I know it's simple, but if I learn how to do that I could go onto harder stuff. Thank you very much! Daniel

function xyz
x = uicontrol('style','edit','units','normalized',...
'position',[.18 .5 .2 .2],'callback',@xCallbackFcn,'tag','x')
y = uicontrol('style','edit','units','normalized',....
'position',[.4 .5 .2 .2], 'callback',@yCallbackFcn,'tag','y')
z = uicontrol('style','edit','units','normalized',...
'position',[.62 .5 .2 .2],'tag','z')
set(x,'string',0)
set(y,'string',0)
set(z,'string',0)
function xCallbackFcn(hObject,eventdata)
x = str2double(get(findobj('tag','x'),'string'));
y = str2double(get(findobj('tag','y'),'string'));
z = x + y;
set(findobj('tag','z'),'string',z)
function yCallbackFcn(hObject,eventdata)
x = str2double(get(findobj('tag','x'),'string'));
y = str2double(get(findobj('tag','y'),'string'));
z = x + y;
set(findobj('tag','z'),'string',z)
