Excel 2010 :: Automatically Copy Multiple Workbooks Into One

I am attempting my first working macro. I am currently using Excel 2010 on Windows XP. Here is what I am attempting: I need a very user friendly macro that will allow my staff to click on a button to run the macro. Each month they receive multiple workbooks from one of our clients. The workbooks are always stored in the same location. I need the macro to go in and pick up the first worksheet of each workbook and copy it into a new workbook. Each original sheet1 of each workbook should have its own sheet in the new workbook, i.e. if there are 5 original workbooks then the macro should create one workbook with 5 sheets. Here is the programming I have been using:

Sub GetSheets()
Path = "C:Documents and Settingse462863My Documents
utterblotter"
Filename = Dir(Path & "*.xls")
Do While Filename ""
Workbooks.Open Filename:=Path & Filename, ReadOnly:=True
For Each Sheet In ActiveWorkbook.Sheets
Sheet.Copy After:=ThisWorkbook.Sheets(1)
Next Sheet
Workbooks(Filename).Close
Filename = Dir()
Loop
End Sub

This works, but I am running into a few problems. I need to create a "run" button but I'm unsure how to build it. Also, when I run this macro there are tons of extra sheets and the worksheets tend to duplicate. I am wondering if the "loop" is picking up more than I need.
