What I tried and what worked in Wings3D is:
create a model
select model
right mouse click on model 'uv mapping'
in the upcoming right window rightclick somewhere and do
segment by projecton
then
continue by projection
there is the unwrapped texture. now rightclick on texture and do
create texture
then save as .obj., this will save the model and the texture with the correct uv coordinates, and you can edit the corresponding .png.

Dirk
