    How to make this script to quickly set specific weights? (Screenshot attached)

    I have an idea how to get a faster workflow when assigning weights in edit mode, and would like to know how hard this would be to make in python as an addon:

    I'm manually setting weights using this method:
    1) Select one or more vertices
    2) Select a vertex group
    3) Choose a weight
    4) Click Assign

    If I'm not happy with it, repeat 3-4 until I'm happy. This can be quite cumbersome.

    With my addon, it would be one less step, like this:
    1) Select one or more vertices
    2) Select a vertex group
    3) Click 20 - And 0.2 is assigned in one click

    If I'm not happy with it, I just click another value. It would save a lot of time for me.

    And as an extra bonus, if this is possible, there is also a Liveweight slider, that updates the vertex group as I drag the slider, and I see the result right away. Pretty much like the Vertex weights in the Properties panel, but this affects all selected vertices.

    Would this be possible, and where would I start? I have never coded anything in python, but I've been coding for a long time, mostly PHP and Javascript, so I think I can figure out the basics, if I get some pointers.

    Also, is it possible to put this inside the Vertex Group section, or does it need to be in a separate panel? I've attached a rough screenshot of my idea as a separate panel.

    EDIT: After some fiddling, this is what I got, however the buttons are not showing up. Why?

    Also how do I assign weights to the current vertices in the selected group? I will study the documentation a bit more, but any help would be nice :)
