If it gives you an error then tell us what the error is!! It makes it a lot easier for us to help you fix it rather than us trying to work out the error just by looking at a snippet of code.
In this case though it is clear enough to see...

SS = handles.( ['push' num2str(i)] );
should work. You should use more meaningful variable names though.
Your code includes 2 mistakes - one trivial one that you include a '_' in your attempt to create the pushbutton name and one coding mistake:
SS is a string in your code. The set call requires the pushbutton object - i.e. the object stored on handles, not the name of it. You can put together a field name dynamically as I did above using ( ) syntax on the struct. The result of this will then be the pushbutton object, not a string.
