Translated (including errors & comments):

import core.sys.windows.windows;
import core.sys.windows.commctrl;
import std.stdio;

HINSTANCE hInst;

extern(Windows):

BOOL DlgMain(HWND hwndDlg, UINT uMsg, WPARAM wParam, LPARAM 
lParam) nothrow
{
     switch(uMsg)
     {
     case WM_INITDIALOG:
     {
     }
     return TRUE;

     case WM_CLOSE:
     {
         EndDialog(hwndDlg, 0);
     }
     return TRUE;

     case WM_COMMAND:
     {
         switch(LOWORD(wParam))
         {
             //case BT_1:
             //{
             //    writeln("Ola Mundo!");
             //}
         }
     }
     return TRUE;
     }
     return FALSE;
}


int WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, LPSTR 
lpCmdLine, int nShowCmd)
{
     hInst=hInstance;
     InitCommonControls();
     return DialogBox(hInst, MAKEINTRESOURCE(IDD_DIALOG1), NULL, 
&DlgMain);
}
