谁能帮我用VB编个小程序啊？

我没有接触过VB，但是老婆他们学，要编一个鸡兔同笼的问题，就是输入总共的脚的数量与鸡和兔的总数，下面可以算出有多少只鸡、多少只兔并显示出来，这问题很简单，不浪费多少时间的，各位大虾帮个忙了，拜托了，只要把代码给我就好了

Private Sub Command1_Click()
Form1.AutoRedraw = True
Cls

Dim numCh, numRa As Integer '定义 鸡的数目与兔的数目
Dim numFeet, numTotal As Integer '定义脚的总数与 总的只数
Dim bool1, ok As Boolean

numTotal = val(InputBox("请输入总只数："))
numFeet = val(InputBox("请输入脚的总数："))
'判断输入是否合理，
Do While (numFeet Mod 2 <> 0) Or (2 * numTotal > numFeet)

MsgBox ("脚的总数 或者 总的只数前皮 输入不正确，请重新输入")
numTotal = val(InputBox("请输入总只数："))
numFeet = val(InputBox("请输入脚的总慧困差数："))
Loop
'进行尺裤计算
bool1 = False
ok = False
For numRa = 0 To numTotal
numCh = numTotal - numRa
bool1 = (numRa * 4 + numCh * 2 = numFeet)
If (bool1) Then
ok = True

Print "The number of Rabbits is", numRa
Print
Print "The number of Chickens is", numCh
Print
Exit For
End If
Next numRa
'判断是否完成
If (ok) Then
Print "求解完毕!"
Print
Else
Print "无法求解！"
End If

End Sub
