To dumb for XML UI

[Onibubu]

Hi,

First about my background. I did learn C##/Java and also have written code in a lot of other languages.
LUA isn't really my problem.
My problem is XML.
I never have used it, never needed it and I simply doesn't get how to make an UI in Eso...

All I want is a window with 2 Buttons.
When you click on a button a lua function is called, when you click on the other button another lua function is called.

My Problem:
My Button is as big as the whole window... and I dont know a good texture to "fill" the button.

<GuiXml>
    <Controls>
        <TopLevelControl name="raidRegrouper">
            <Dimensions x="400" y="200" />
            <Anchor point="CENTER" />
 
            <OnUpdate>
               AddOnUpdate()
            </OnUpdate>
 
            <Controls>
                <Backdrop name="$(parent)BG" inherits="ZO_ThinBackdrop" />
				
				<Button name="$(parent)save" font="ZoFontWindowTitle" verticalAlignment="CENTER" text="Anus">
					<Anchor point="TOPLEFT" />
					<Dimensions x="50" y="200" />
					<FontColors normalColor="FF0000" />
					<Textures normal="/esoui/art/buttons/accept_over.dds" />
					<AnchorFill />
				</Button>
				
            </Controls>

        </TopLevelControl>
    </Controls>
</GuiXml>

If any one has a idea i would be gratefull!
