function exampleEditEnable
%Build stuff
hFig = figure;
hBut = uicontrol('style','push','units','norm','position',[0 0 0.3 0.1],'enable','off','string','can''t touch this'); %a button
hEdit = uicontrol('style','edit','units','norm','position',[0.5 0.5 0.3 0.1],'string','edit me, I dare you!','callback',@enableButton); %an edit box
function enableButton(varargin)
set(hBut,'enable','on');
set(hBut,'string','can touch this');

To translate this into GUIDE just use handles.edit and handles.pushbutton etc.
