Hey Ruccus,
If I remember right (and seeing as you have the latest version of Wings), you can export UV data onto your model. In fact, I've just tried it and it works just dandy with v0.98.29b.
Steps:
1) Make a cube.
2) Select all the faces and right click. Select UV Mapping > Direct.
3) In the window that pops up, experiment by selecting different faces, right clicking, and apply a chart to the face (I'm no pro on the best way to approach this, so just experiment).
4) When you've assigned all the faces a chart, right click, Continue > Unfolding.
5) If the resulting 2D image is good enough for you, go ahead and right click, Create Texture.
6) Export your model to .3DS or whatever.
7) Load up LithUnwrap (if you can't find it [google it], then let me know and I'll email it to you), open up the model, and export the UV data to a bitmap.
8) Open up a paint program, and fill in the lines with your texture. Save the bitmap.
9) Load up LithUnwrap again, and modify the material for your object (on the right side, expand Materials, right click on the material, Properties).
10) For diffuse map, set the map type to bitmap, click Properties, Change, and load your bitmap.
11) Your model should be textured.
12) Export to the file type of your choice.
That's how you texture in Wings3D anyways. It can be a bit confusing if you're not sure how to go about it, but it's pretty easy once you know how to handle it. Let me know if you have any more problems, or need some screenies to help you
