I ended up with using Exergist's great program as the framework. Therefore a lot of code is borrowed from that. I created dynamic buttons to avoid having to write out 52 buttons. Below code with adaptions. See link posted in previous thread for original post located in Inline Functions section.
// C# inline function for retrieving user input & preprocessing
Marker: GotoInline
Inline C# Function: Display UI for getting input & process result, wait until execution finishes
// Check if user provided relevant input
Begin Text Compare : [~~UserInput] Has Been Set
Begin Text Compare : [~~isCancel] Equals 'No'
// Output retrieved information
Write [Blue] 'Letter selected is: {TXT:~~UserInput}' to log
Quick Input, '{TXT:~~UserInput}'
Jump to Marker: GotoInline
Else
// Output info to event log
Write [Red] 'Exited Alphabet Form' to log
End Condition
End Condition

It does exactly the same thing as the previous example without using inline functions, but with buttons!
