Have you seen the videos that are on this website: http://www.espruino.com/ESP8266
They use a 'shim' PCB that you can buy, but it's a nice easy way to get a very compact system.
Either that or you can connect just 5 wires to an ESP01 module - shown in the table here: http://www.espruino.com/ESP8266#wiring-up
If you have a pinned Pico and some patch wires then you can do it without soldering at all.
