GUI library for DMD 2.090 or DMD 2.091

[Phrozen]

I'm too new to DLang and I have a lot to learn. Probably that's 
why I have a lot of difficulties. Has anyone tried using a GUI 
library to the latest DMD 2.090 or DMD 2.091? I plan to use this 
language for a specific Thermal calculator application for 
Windows, but for two days I've been struggling with dub and 
elementary examples in GUI libraries. I need something simple - a 
modal window with 3 buttons and a two text boxes. So far I have 
tested DWT, TKD, DFL, dlangui without success.
Can anyone help me with advice or some more recent tutorial. 
Thank you!
