I've recently found a android app wich converts 5 pictures (light from top,left,upper,right,lower).
Here's a link to the site: http://normalmapcamera.com/
I would like to know if there is a desctop programm to do the same thing?

You can always do it manually.

Hard mode: take two more shots in addition to what he describes and with even light, one with cross-polarization (polarizers in-phase on both your lens AND light source) and one without, and make sure exposure stays the same. Subtraction blend these shots and bam! - perfect specular map.

By the way, the polarized shot works pretty well for the diffuse since it lacks reflections and should be evenly-lit. It also pays to try and avoid sub-surface scattering by setting your subject up against a black velvety fabric. In fact, you should try and black out as much of your surroundings as possible.
