Can't get out of wireframe mode.

Iodine, welcome to our community.

That is not really the wireframe view, it's a transparent texture. I don't know it that should be the right behaviour.

In order to avoid that, in the options for Create Texture include Draw Faces option. It will use the face object color to draw.

To get access to the UVEditor again, just select one mapped face and go to main menu Windows->UV Editor window, then you can recreate the texture.
