I'm all in for a free GUI application
I'd have done one myself only I don't program C++
Here's the Visual Basic Code for creating a window / button / textbox / whatever*
(Still think BlueGUI is worth the price?)
Public Declare Function CreateWindowEx Lib "user32" Alias "CreateWindowExA" _
(ByVal dwExStyle As Long, _
ByVal lpClassName As String, _
ByVal lpWindowName As String, _
ByVal dwStyle As Long, _
ByVal x As Long, _
ByVal y As Long, _
ByVal nWidth As Long, _
ByVal nHeight As Long, _
ByVal hWndParent As Long, _
ByVal hMenu As Long, _
ByVal hInstance As Long, _
lpParam As Any) As Long
I can't imagine it's much different in C++.
