Does anyone know where I can find connection wires with a .187" female disconnect to a Raspberry Pi female GPIO pin header already attached? I'd like to connect a few arcade buttons to the RPi GPIO pins to control a project I'm working on. I've found places that sell wires with one or the other connection, but I haven't been able to find anyone who sells the pair matched up.
This is my first project, and my costs have already exceeded my original plans. At this point I'm really hoping not to spend the money for a nice crimping tool and buy an inventory of wire and terminals. If I can improve the terminology of my question, I would also appreciate input on that
Here are a few pictures (from Adafruit's website) to illustrate what I mean. I want to connect a few of these:

directly to the RPi's GPIO pins, using one of these:
