Hi Antonette,
Here is a way to do it using GUIDE.
Add the variable to 'handles' parameter of the 'OpeningFcn' of the GUIDE as shown below,
function Test_OpeningFcn(hObject, eventdata, handles, varargin)
% This function has no output args, see OutputFcn.
% hObject handle to figure
% eventdata reserved - to be defined in a future version of MATLAB
% handles structure with handles and user data (see GUIDATA)
% varargin command line arguments to Test (see VARARGIN)
% Choose default command line output for Test
handles.output = hObject;
handles.n=0;
% Update handles structure
guidata(hObject, handles);
And for the button callbacks add the code as follows and the following code increments and displays the value of 'n' in the command window when the button is clicked.
function pushbutton1_Callback(hObject, eventdata, handles)
% hObject handle to pushbutton1 (see GCBO)
% eventdata reserved - to be defined in a future version of MATLAB
% handles structure with handles and user data (see GUIDATA)
handles.n=handles.n+1;
disp(handles.n);
guidata(hObject,handles)
function pushbutton2_Callback(hObject, eventdata, handles)
% hObject handle to pushbutton1 (see GCBO)
% eventdata reserved - to be defined in a future version of MATLAB
% handles structure with handles and user data (see GUIDATA)
handles.n=handles.n+1;
disp(handles.n);
guidata(hObject,handles)
Hope this helps you.

Sindhu
