Is this what you want? (note: different look and feel for Windows OS)

 button = questdlg('Are you sure to quit?','Question','Yes','No','No');
 switch button
    case 'Yes',
        quit
    case 'No',
        quit cancel;
 end

A similar example is also provided by the Matlab help documentations. Have a look at it by typing "help quit" and hit enter at the Matlab Command Window. Sometimes do a little research by using the Matlab help documents could solve many problems.
