Lets bump a 30 minute old topic! On Topic: From what I have done, press f10 in mission editor to make Gui's. Just keep at it and you will find the button maker. Since its a main aspect, it shouldn't be too hard to find.
Ok if you read my post...
I can make buttons and I can make windows
So I already kow how to make buttons , oh, and sry for da bump :( when I went to check on it it was the fourth one down the list already then it was moved
I'd suggest looking at simple GUIs that are already in Blockland, learn how the hierarchy of objects works on the right, familiarize yourself with the common settings used for controls (like base\client\ui\button1 for the GuiBitmapButtonCtrl) and then start experimenting. You can use ctrl+c and ctrl+v in the gui editor, so that might help.
Ok I'll try that, and one more quick questtion:
How do I load a GUI? There is no load option and it doesn't popup.
EDIT: And by
how do I make the button like a part of the window.
I mean how do I make a window the parent of a button?
