Powershell and Forms

I need some help. I am creating a form that emurates all the drives with some input boxes so items can be change such as lables. It disaplys on the form correctly looks nice but I have don't have any idea how to get repeaded data like that on a form into an array so that I can reconfigure the drives.  Any sugestions would be great.

I did find out that adding  "$objArray += $objDriveLetter" at the end seems to capture the input boxes but it is not in a useful format.

Function DiskDrives{

    $RowSize = 100
    $RowSize = 0
    $global:i = 0
    $Drives = @("C","D","L","I","T","U")
    $DriveLabels = @("","DATA","LOGS","INSTANCE","TEMP","BACKUP")
    $objArray = @()
    $x = @()
    $global:QUIT = $false
    #Get Drives
    $Disks = get-disk | sort Number

    Add-Type -AssemblyName System.Windows.Forms
    $Form = New-Object system.Windows.Forms.Form
    $Form.Text = "Drive layout Specs"
    $Form.Size = New-Object System.Drawing.Size(350,350)
    $Font = New-Object System.Drawing.Font("Times New Roman",12,[System.Drawing.FontStyle]::Italic)
    # Font styles are: Regular, Bold, Italic, Underline, Strikeout
    $Form.Font = $Font

    #Title
    $Label = New-Object System.Windows.Forms.Label
    $Label.Text = "Number     Letter        Label               Size"
    $Label.AutoSize = $True

    Foreach($Disk in $Disks){
        $global:i += 1
        $RowSize += 30

        #Add Drive Number box
        $DriveNum = New-Object System.Windows.Forms.Label
        $DriveNum.Location = New-Object System.Drawing.Size(30,$RowSize)
        $DriveNum.Text = $Disk.Number
        $DriveNum.AutoSize = $True
        $Form.Controls.Add($DriveNum)
        $objArray += $DriveNum

        #Add Drive letter box
        $objDriveLetter = New-Object System.Windows.Forms.TextBox
        $objDriveLetter.Location = New-Object System.Drawing.Size(80,$RowSize)
        $objDriveLetter.Size = New-Object System.Drawing.Size(30,20)
        $objDriveLetter.Text = $Drives[$global:i-1]
        $Form.Controls.Add($objDriveLetter)
        $Form.Topmost = $True
        $objArray += $objDriveLetter

        $DriveSize = New-Object System.Windows.Forms.Label
        $DriveSize.Location = New-Object System.Drawing.Size(235,$RowSize)
        $DriveSize.Text = $Disk.Size / 1GB
        $Form.Controls.Add($DriveSize)
        $objArray += $DriveSize
}
    $RowSize += 50
    $SubmitButton = New-Object System.Windows.Forms.Button
    $SubmitButton.Location = New-Object System.Drawing.Size(60,$RowSize)
    $SubmitButton.Size = New-Object System.Drawing.Size(75,23)
    $SubmitButton.Text = "Submit"
    $SubmitButton.Add_Click({$Form.Close()})
    $Form.Controls.Add($SubmitButton)

    $CancelButton = New-Object System.Windows.Forms.Button
    $CancelButton.Location = New-Object System.Drawing.Size(150,$RowSize)
    $CancelButton.Size = New-Object System.Drawing.Size(75,23)
    $CancelButton.Text = "Cancel"
    $CancelButton.Add_Click({$global:QUIT = $true;$Form.Close()})
    $Form.Controls.Add($CancelButton)

    Form.Controls.Add($Label)
    $Form.ShowDialog()

    if($global:QUIT -eq $true){Exit}
