Rhinoscript/SDK question

Hi,

This is not a GH question but it seems this is the most active Rhino forum so I'll put it here anyway.

I'd like to put a small interface for my rhinoscript into the object properties window in Rhino by adding another tab with a couple of sliders and number fields for user input.
It seems as this has to be achieved by scripting using the SDK. I don't know even where to start, can someone help me?
