Here is a PowerShell script that does what you wish.
$Computer = "localhost"
$Class = "Win32_Share"
$Method = "Create"
$name = "foldername$"
$path = "C:\Folderpath"
$description = "This is shared for me to test"
$sd = ([WMIClass] "\\$Computer\root\cimv2:Win32_SecurityDescriptor").CreateInstance()
$ACE = ([WMIClass] "\\$Computer\root\cimv2:Win32_ACE").CreateInstance()
$Trustee = ([WMIClass] "\\$Computer\root\cimv2:Win32_Trustee").CreateInstance()
$Trustee.Name = "EVERYONE"
$Trustee.Domain = $Null
$Trustee.SID = @(1, 1, 0, 0, 0, 0, 0, 1, 0, 0, 0, 0)
$ace.AccessMask = 2032127
$ace.AceFlags = 3
$ace.AceType = 0
New-Item -type directory -path $path
$Acl = Get-Acl $path
$Ar = New-Object system.security.accesscontrol.filesystemaccessrule("user\domain","Write","Allow")
$Acl.SetAccessRule($Ar)
Set-Acl $path $Acl
$ACE.Trustee = $Trustee
$sd.DACL += $ACE.psObject.baseobject
$mc = [WmiClass]"\\$Computer\ROOT\CIMV2:$Class"
$InParams = $mc.psbase.GetMethodParameters($Method)
$InParams.Access = $sd
$InParams.Description = $description
$InParams.MaximumAllowed = $Null
$InParams.Name = $name
$InParams.Password = $Null
$InParams.Path = $path
$InParams.Type = [uint32]0
$R = $mc.PSBase.InvokeMethod($Method, $InParams, $Null)
switch ($($R.ReturnValue))
{
0 {Write-Host "Share:$name Path:$path Result:Success"; break}
2 {Write-Host "Share:$name Path:$path Result:Access Denied" -foregroundcolor red -backgroundcolor yellow;break}

default {Write-Host "Share:$name Path:$path Result:*** Unknown Error ***" -foregroundcolor red -backgroundcolor yellow;break}
}
I cribbed it and patched it together from a couple of other sites, 1 and 2. It works on my Windows 7 machine. For more information on the filesystemaccessrule object, look here.
