Hello,
I want to try out a small contribution to the JDK and wanted to
build the JDK first, before I change the code.
I forked and cloned the jdk following the instructions at The OpenJDK
Developers' Guide – OpenJDK Developers’ Guide
<https://openjdk.org/guide/#cloning-the-jdk>
I am on Windows 11.
These instructions are given on the page but I am unsure which of these
to execute since I have already forked and cloned the git repo
You jumped from the cloning instructions to the building instructions,
which are given for a particular Linux development system. You need to
adjust for Windows - see the doc/building.md file in the repo you cloned.

Do I still need to do the wget?
The wget is to download a boot JDK for the build to use. If you already
have one installed then you don't need to download one. Also wget is a
Linux utility not Windows.
Also, I wondered if I should use book jdk-17 instead of jdk-16 as in the
instructions above.
If you are building mainline JDK then at this stage you need a JDK 22
boot JDK.
HTH.
