2.5 Panel controls

Coding Python Support
1

Not done any blender python programming before and decided to start with blender 2.5

I have created a script that I like and would like to have a UI associated with it.

I am using the hello world panel example

import bpy

class OBJECT_PT_hello(bpy.types.Panel):
    bl_label = "Hello World Panel"
    bl_space_type = "PROPERTIES"
    bl_region_type = "WINDOW"
    bl_context = "object"

    def draw(self, context):
        layout = self.layout

        obj = context.object

        row = layout.row()
        row.label(text="Hello world!", icon='WORLD_DATA')

        row = layout.row()
        row.label(text="Active object is: " + obj.name)
        row = layout.row()
        row.prop(obj, "name")

I would like to add another control that allows me to choose a value between 1 and 360 (or any other number)

how would I do this?

Thanks
