Are you looking to create the trees in a random position or define where you would like to put them when the button is pressed?
If you want to limit the number of trees than you could use a "count." You can set this in the code or have it changeable in a cmds.intFeild. So when you press the button it should increase the "count" value by one.
You can establish it simply at the top:
count = 0
Then in side of the code have an if statement that checks if the count is greater than or equal to the number you want it to stop at:
Code:
if count >= <some_value>:
print "max tree limit"
else:
<run the rest of the code>
count += 1
For the button image you may want to use the "symbolButton" command which will let you use the "image=" flag and you can link the image from your directory. I hope some of this helps. Let me know about the placement and I'll see what I can do!
