Which morphic interfaces? You already tried the programmatic ones, but
there's the EToys (tile scripting) or you could also do some simple plugging
of behavior at the button level.
I'll guess EToys. I'll also assume you have 3.2, since I'm too lazy to find a
3.1 to try this on. Don't know if it's changed much from 3.1 to 3.2.

I don't know what kind of text field you were using. But let's assume it's a
TextMorph. Grab one out of your Objects tool or flap.
Click the halos open, then choose the viewer button (the eyeball).
In the "basic" category there's a line that looks something like:
Text's numericValue <- 3
Grab the arrow of that and drag onto the desktop. You now have a script that
will make the numeric value 3. That's not what you want, so drag from the
same line on the tile that says "numericValue". Drop it on top of the 3 in
your new script.
You'll see an arrow to the right of numericValue in your script. Click it. It
will expand to + 1.
You're done with the script. Click on the (!) button to make sure that it
works. Good. Now to make it a button...
Click on "Text" in the top row of your script to see a menu. Choose "button
to fire this script". Now you have a button that will increment the number.
You can change the button's label with its menu.
You can then stick the text field and button into something if you want.

Please don't do that.
