Try reading the getting started section of GUI's , and have a look in to these lines:

% Create the Audio recorder Object

>> rec = audiorecorder(22050, 16, 2);

% Create a Function to create the GUI

function test(rec)
  f= figure ;
  uicontrol(f,'style','pushbutton','position',[10 10 200 20],'String','Record','CallBack',@buttonCallback) ;
  function buttonCallback(~,~)
      disp('Recording... start talking');
      rec.recordblocking(2);
      disp('Stopped.');
  end
end

% Execute the function with the object as a parameter

>> test(rec)

thanks that helped , do you know how to combine it with rest of my code ? I want the code be waiting for the pushbutton then continue excuting ,

[x1,fs]=wavread('C:\Users\user\Documents\MATLAB\red.wav');

X1=x1(:,1);

rec = audiorecorder(22050, 16, 2);

test(rec);

play(rec);

y= getaudiodata(rec);

Y=y(:,1);

z1=xcorr(X1,Y);

maxred=max(z1);

length1=length(z1);

t1=-((length1-1)/2):1:((length1-1)/2);

t1=t1';

max5=15; all=[maxred max5]

m=max(all);

if m<=maxred

soundsc(wavread('red.wav'),22050)

disp('red');

else soundsc(wavread('denied.wav'),8000)

disp('denied');

end
