How about you use menu() to let the user select the emotion. Then you pre-create images, like draw them in Photoshop or collect them off the web. Then depending on what button they click, you use imread() and imshow() to display the chosen emotion image?

button = menu('Pick emotion', 'Happy', 'Sad');
if button == 1
    img = imread('happy.png');
elseif button == 2
    img = imread('sad.png');
end
imshow(img);

That would be great and easier to do if i just create de images, but i think the images need to be drawn by the software, like a simple smiley face than a frowny face and so on . :(

Then you need section 5 of the FAQ where it shows you how to draw simple shapes like ellipses and arcs. http://matlab.wikia.com/wiki/FAQ#toc
