You're really asking two different questions. Maybe even 3. A plugin is just a packaged bundle of tiddlers. It's not too hard to make with node. Make a directory "plugins/myplugin" below your node-based TW folder and then put whatever tiddlers you want in myplugin. Add a file "plugin.info" (see tiddlywiki for details how to populate plugin.info) and run node.js. Navigate to plugins and you'll see your new plugin. You can export if from there if you want.
A button that invokes javascript would need a widget or a javascript macro. The easiest way to make a javascript macro is to look at an existing one (e.g. $:/core/modules/macros/now.js) and modify it accordingly. For starting things during boot, type "startup" into tiddlywiki.com for information on how to set up tiddlers that get invoked at startup. However it's possible that what you really want is $:/tags/RawMarkup . Be aware that if you put JS code into RawMarkup inside a plugin that you will have to save and reload your TW file twice. But you may actually want help with writing widgets. If you find any simple, understandable guide to writing widgets please let me know! Chris Hunt (?) had a guide, but now you have to find it on the internet archive, and the code he uses doesn't match the current code, which is confusing.
