Sample code for nice GUI for imageX? (to automatically deploy WIM-files using Windows PE)

I currently use this simple batch-file to deploy an image to our workstations:

ECHO HALLO
y:
cd \
diskpart /s diskpartcmds.txt
imagex.exe /apply y:\image.wim 1 c:
bootsect /nt52 c:

(Y: is a mounted network share, dispkatcmds.txt is

select disk 0
clean
create partition primary
select partition 1
active
format quick
assign letter=c
exit

)

This works absolutely well, it runs in a console window after WinPE booted via PXE and shows progress. I would only like to have a nice GUI (just showing tasks and progress, no interaction!) that is shown instead of the console while the image is deployed with a progress bar.

Does someone have something already? Is there a complete .NET wrapper (I can use mono installed on Y:!) for ImageX?

Unfortunately there is only one article to be found about imagex.dll

Sorry for posting such a selfish lazy question about something purely cosmetic that I would probably be able to write if I had a lot of time), but I can try and maybe someone learns from this question about imagex?
