Back about 25 years ago when I made and sold maple poppers for saltwater stripers and bluefish (junior high pocket money!), I gundrilled them on a lathe and did a through wire. Broke a lot of bits in maple, then I figured out to use a larger bit and to close out the larger hole with a sleeve ferrule (looks very nice too as a by-product). If you do it right you can loop the wire at the front, and pass one leg out of the rear hole and one leg out of the belly hole (belly hole is angled forward). Then you just twist loops into the wire at the exits and you're ready for trebles and split rings.
All of the freshwater stuff I've done with basswood has just been eye screws, which is plenty strong if you get decent quality hardware. Balsa too, if you get longer shank eye screws. I have laminated before but it's a pain in the ass to carve with a glue seam and (and a grain boundary) and it's usually only necessary if you have a very slender section that could split from sideforce on an eye screw.
I haven't made a bait in almost 20 years, I should really get back into that. I stopped obsessively fishing in high school because we moved to VA and reservoirs aren't as fun. I really stuck to poppers, prop baits, and walkers though, because I was a die hard New England topwater guy.
