I have two buttons in my figure window, and i want to perform different operation for this two button, but i don't know how to detect which button is pressed? Thanks a lot.
f = figure;
u1 = uicontrol('Style','push', 'parent', f,'pos',...
[750 50 60 60],'string','Back','Enable','off','Callback','uiresume(gcbf)');
u2 = uicontrol('Style','push', 'parent', f,'pos',...
[830 50 60 60],'string','Next','Enable','off','Callback','uiresume(gcbf)');
align([u1,u2],'distribute','bottom');
if buttonBack is pressed...?
.....
end
if buttonNext is pressed..?
....
end

You need to define separate callback functions, rather than 'uiresume(gcbf)' like you did.
I suggest you look at this GUIDE tutorial which will make it a lot easier than trying to manually create dozens of controls one at a time for your GUI, which can be rather tedious since, as you can see, there are a lot of input arguments you have to worry about. http://blogs.mathworks.com/videos/category/gui-or-guide/

nice link! i am still learning. Thanks. i also think that writing all controls at a time is very difficult for further maintenance.
