One of the very basic HTAs published on that site:
<head>
<title>HTA Test</title>
<HTA:APPLICATION
APPLICATIONNAME="HTA Test"
SCROLL="yes"
SINGLEINSTANCE="yes"
>
</head>
<script language="VBScript">
Sub GetOSVersion
strComputer = "."
Set objWMIService = GetObject("winmgmts:\\" & strComputer & "\root\cimv2")
Set colOperatingSystems = objWMIService.ExecQuery _
("Select * from Win32_OperatingSystem")
For Each objOperatingSystem in colOperatingSystems
DataArea.InnerHTML = objOperatingSystem.Caption & " " & _
objOperatingSystem.Version
Next
End Sub
</script>
<body>
<input type="button" value="Operating System" name="run_button" onClick="GetOSVersion">

<span id = "DataArea"></span>
</body>
