Most clubs start off with Scratch, which can be accessed via a web browser, so all you would need for your club is access to PCs or laptops. You can find out more about the system requirements for Scratch on their website, where you can also download an offline version.

For our Python and HTML and CSS projects, we recommend using Trinket to write the code, which can be used in a web browser. Both Scratch and Trinket are free to access.
