Ah, you didn't say you wanted to recreate the bitmap into a vector. You said "wireframe" which is technically something different.
You can use the Trace program, but honestly, you'll get the best results by manually redoing it in Draw. That's why you should not use a bitmap editor to create logos, etc. Always create from scratch in the vector app and export out to bitmap format(s) as needed.
You'll want to import the bitmap and then use the bezier tool to create the various elements of the bitmap.
