Getting Started With Script I would like to manually write a few locking and unlocking scripts to get a deeper feel for that part of the network.  What is the simplest step-by-step set of instructions to set up everything needed to use Script in Windows, on regtest or some other testnet?  Is it possible to do this in Bitcoin-qt, or is working in the command-line a necessity?
You might want to check out btcdeb from kallewoof. It's a set of tools used to construct or debug bitcoin script.
