Blender, because I wasnt able to figure the other ones out.... :/

Ah, well in that case I can not help you.
I suggest you go to youtube and make a search for Blender UVW mapping tutorial, this will basicly convert your model into a 2D plane which you can then pain ontop of using an image editing program such as photoshop or gimp, then applied to your model as a texture. This texture then needs to be converted into a .dds format which can be done with various plugins.
