If you buy a black 'picotouch SMD' board from my Tindie store, the resistors are soldered for you, so you only need to solder the Pico.
If you're building one by hand, you will need:
It's not too bad! A pretty easy first-time SMD soldering project. Here's how to solder the Pico down. The technique is: line up the Pico solder one corner, solder the other, then finish all the rest. In the video you see I don't get it aligned perfectly straight (hard to see around the camera), but it still works great! (Youtube version of the below video)

Install CircuitPython
Install CircuitPython libraries onto Pico
pip3 install circup
circup install adafruit_midi adafruit_debouncer adafruit_ticks
adafruit_midi

, & adafruit_ticks
librariesCIRCUITPY/lib
folder on the Pico.Install picotouch code.py
cp picotouch/circuitpython/picotouch/code.py /Volumes/CIRCUITPY/code.py
code.py
on your Pico.There's other things you can do with the picotouch board.
Use it as a MIDI slider bank
Install
picotouch_midislider/code.py
instead of the regular picotouch code.py.
Use it as a HID keyboard macropad
picotouch_macropad/code.py
It's early days, but it's a start at that idea
