Hack A PCB

Is there a good way to solder or just connect wires directly to traces on a one sided PCB?

What are you trying to achieve? Please give some more detail. Pat. Pending

I want to use the buttons of a SNES controller to control a mod I'm working on.
If you need to solder to a trace on a previously masked board (green covering over the traces) you need to first remove the masking from the area you need to solder. Use an Exacto knife to carefully scrape the making from the trace area. Be very careful not to cut the trace! Then tin the trace with a tiny amount of solder (melt solder onto the trace with the soldering iron.). I also like to tin the wire in advance if it's multistrand wire. This allows you to solder it to the trace very quickly preventing overheating of the trace.
. Yes! Tinning is an excellent idea.

I've often made single sided boards by cleaning them with steel wool or large rubber "pen erasers", then drawing the lines of the schematic as traces with a permanent marker, then etching it, then soldering all the parts and wires where they go, without drilling any holes. It's like "surface mount" but with the older sizes of parts, such as DIP chips, resistors, diodes, capacitors, etc. Good for making just one of something really quick after breadboarding it and drawing the schematic. I like it better than perf board projects.
. Hmmmmmm. Never thought of using DIPs as SMDs. Do you have to bend the leads or anything? Or just set it on the PCB and put a dab of solder on the pin tip?
Bend the thin part of the DIP chip leads to rest on the traces... unless they're gone. It's convenient to salvage some chips by cutting them off a board instead of solder-sucking them, with a dremel... especially 40 pin DIP's, like retro processors (Z-80,6502,etc).
. A little disconcerting to know the processors I cut my teeth on are now considered retro. Oh well, getting old is better than the alternative. :)
Cheer up and take care of yourself and don't fear the little number of trips around the sun. I know a 91 y/o farmer who still loves life. Smile, You're alive! Enjoy the day. :)
>>> Or just set it on the PCB and put a dab of solder on the pin tip? >>> I was just thinking this also. Rosen core solder, so you get a little flux with it, but it would have to be quite tiny...might be difficult on, say a 8 pin or greater device
