So your code is:
handles.edit1 = 0;
This way you don't create an object, you simply add a field to the structure "handles", with value 0. I think you misunderstand the concept of handles. A handle is merely a number to refer to an object. The handle itself does not contain any properties. In addition, you can't add properties to an object: all properties are defined by the type of object.
Maybe you want to look at some of these examples: http://www.youtube.com/watch?v=D_hmws6dwgg http://www.mathworks.com/matlabcentral/fileexchange/7598

Let me explain it for an edit box(assuming Tag is 1)
x = get(handles.edit1,'String');
set(handles.edit1,'String',z);
Now similarly use get & set to get & set properties via handles of Objects

If I understood correctly, 'String' is a property? if yes, then you explained how to set and get value of a string. I'm looking how to add 'String' (which is a property) to a handle that doesn't has any properties.
In other words: assume that I'm at the Demo_OpeningFcn (GUI) and I write a s follows:
handles.edit1 = 0;
. . .
how to handles.edit1 add a property?
