Here I added it all to a super easy GUI design creator free to download and use http://www.webpage-maker.com/
load this template into WPM: BB25-Theme-WebPageMaker.zip
use shift click to select more than one, drag n drop images into WPM
workspace will zoom in/out with mouse+Ctrl
copy elements from one page to the other, add new pages
you can add text boxes, click on text boxes then use color picker to color, add color boarder by right click Properties
resize, move, layer
color background by clicking background then selecting color picker
you can preview in browser or just take a screen shot
you can use your normal editor instead as they are just images, or you can use https://www.gimp.org/
find any other source images here C:\bb\Data\Images\MainScreenButtons

you can use free https://www.irfanview.com/ to save in other formats, like the bpm with the pink transparent you can save to gif or png and click on the pink color in the save dialog, this will save as transparent gif or png
you can use print-Screen button on keyboard that paste in irfanview, then select area and ctrl+y to crop
