well in simple, i wrote:
A=['handles.',get(hObject,'Tag')];
set(A,'Backgroundcolor',[0,1,0]);
or
A='handles.pushbutton1';
set(A,'Backgroundcolor',[0,1,0]);
and function 'set' cannot read that A, can you help me? Uncle MATLAB says :
Error using set
Value must be a handle

Why are you trying to construct a string? If you have a structure, then do this:
A = handles.(get(hObject,'Tag'));
And read this:

Try
handles.pushbutton1.BackgroundColor = [0, 1, 0];
