thank you Daniel.

i have tried Dlangui previously and had no luck. but this time i 
could successfully compile my first app. now, i can say level 
zero created.

i couldn't set control's width and height (Button widget) shows 
error. maybe it works a different way.
i used the following code instead, but no effect.

// create some widget to show in window
auto button1 = new Button("btn1", "OK"d).margins(50);
button1.minWidth = 200;
button1.minHeight = 50;
button1.maxWidth = 201;
button1.maxHeight = 51;

also i couldn't compile dlangide. it shows error like every time 
before:

D:\ashit\software\D Compiler\DlangUI\dlangide-master>dub run
