Short answer: Yes.
Gestalt requires a good working knowledge of what the classes already DO, plus a fair bit o' number-tinkering. To this end, use the core classes only, and only allow them to use the two classes they originally selected rather than picking willy-nilly each level.
Example:
Player A wants to be a good fighter and be able to fling fire from his fingertips. (Or, a fingertip-fire-flinging fighter -- Huzzah! Alliteration!). He decides on a Fighter/Mage Gestalt. He gets:
: Warrior Attack Bonus, HP, +2 Fort saves, Weapon/Armor proficiencies, and Fighter Feats.
: Wizard spell progression, selection of spells, +2 Wil saves, and Scribe Scroll.
(Of course, the player must now decide whether or not to forego armor so he can cast his spells...)
Numerically, it's an easy pick... now try Paladin/Monk and see if your numbers add up.
It's a lot of information for teh n00bs to process, since they will essentially be processing info from two classes at once. One idea might be to see if they can agree on one extra class that they all share, and pick their "alternate" class on their own. This would automatically give them a reason for adventuring together -- perhaps they're from the same school/family/organization, or work together -- and gives them a general idea of seeing how each other performs in combat using the same-ish skill set.
