How would I create a GUI with a push button that when clicked, text will appear?

In the callback, would I need to add a text file like;

        % --- Executes on button press in pushbutton1.
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)
open('C:\matlabcodes folder\readme.txt')

Additionally, is there a way to put an active link to a website in this text?

Caitlin - where will the text appear? In a control on your GUI or are you opening a file? Please clarify.

In a control on the GUI: The text should appear after the push button is clicked, once the script is run.

1. Use GUIDE.
2. Place a button.
3. Place a static text.
4. Double click on the text label and set the visible property to off in the Property Inspector.
5. Save the GUI and then go to the editor and go to the push button callback function.
6. Put this line of code:

handles.button1.Visible = 'on'; % Make text appear.
